History - scientific achievements (past and future):
The main areas of research are the study of regional features of the formation and change of engineering and geological conditions in Uzbekistan and the development of a methodological basis for forecasting the development of natural and man-made changes in the geological environment and its regulation with the aim of rational use and protection of resources.
From 1966 to 1985, engineering and geological and geological studies were carried out in Uzbekistan in more than 40 cities and towns (by G.A.Mavlyanov, S.M. Kasymov, A.M. Hudaybergenov, M.Sh. Shermatov, M.A. Tuychieva, N.M. Dzhuraev, A.Dzhuraev, Yu.K.Chernovu, Ya.S.Sadykov, R.T. Yunuskhodzhiev, K.Sh.Nurmukhamedov, etc.) and the increments of seismic magnitude are determined. Engineering geological basis for engineering seismometric work was performed by the staff of the laboratory of regional engineering geology.
From 1968 to 1970 for the seismic zoning of the town of Chirchik, G.A Mavlyanov carried out engineering geological studies and mapped the geotechnical zoning maps, thickness and forecast of subsidence of loess rocks, seismic magnitude for the districts of Chirchik, and described the composition and properties of quaternary sediments. The research results were published in the form of a monograph “Engineering-geological conditions of the Chirchik city”.
Study the seismic zoning of the city of Yangiyul, by M.A Tuychieva carried out engineering geological and mapped of engineering geological zoning, thickness and forecast of subsidence of loess rocks, seismic magnitude, and the composition and properties of quaternary deposits were compiled. The research results are published in the form of a monograph "Features of engineering and geological conditions of the city of Yangiyul", Tashkent, 1985, 256 p.
In 1987, with the participation of employees of the Institute of Seismology of the Academy of Sciences of the Republic of Uzbekistan, studies were completed at the Institute “Hydroingeo” on the theme “Develop and implement scientific and methodological foundations for forecasting changes in engineering-geological and hydrogeological conditions of large industrial cities using the example of Tashkent (Petrukhina, Hudaibergenov, etc. 1987) Scientific and methodological bases for forecasting changes in the relief, engineering-geological and hydrogeological conditions, models of interaction and their types of impact were developed, zoning of the geological environment was carried out according to the intensity of changes in the geological environment and the development of engineering-geological processes, principles of location of observation networks were given. A set of maps was compiled, which are necessary for assessing and predicting changes in the geological environment.
Over the past 50 years in the cities of Uzbekistan there has been an intensive construction of industrial civil buildings and structures, industrial enterprises. Multi-storey buildings, transport lines, subways, large collectors, gas pipelines, water pipelines, sewer network were built, the irrigation and collector-drainage network was reconstructed, and other types of economic impact on the geological environment were carried out. This is associated with the formation and development of negative geological processes that adversely affect the geotechnical conditions of the territories, such as waterlogging, subsidence, suffusion, erosion, gullying, salinization and waterlogging, pollution of the atmosphere, surface and groundwater, soil and vegetation.
Over the past 60 years, a number of doctoral dissertations have been carried out in Uzbekistan in the field of engineering seismic geology. S.M. Kasymov (1983) developed the theoretical and methodological engineering-seismic-geological foundations of detailed regionalization (JEM) and microzoning (SMR) in connection with the forecast of seismic hazard on the example of the territory of East Uzbekistan. The main engineering seismic and geological factors affecting the seismic intensity of earthquakes are identified. A rational complex of research methods for compiling an engineering-seismic-geological basis for JEM and SMR was developed. Schemes of engineering and seismic geological basis for the region, the territory of large cities and hydraulic structures have been drawn up. The principle has been developed; taxonomic units of engineering and geological and geological zoning of large regions have been substantiated and distinguished.
A.M. Hudaibergenov (1989) identified engineering-geological patterns and developed principles for assessing the territory of cities and urban agglomeration of Uzbekistan. He established the patterns of formation of engineering-geological conditions associated with zonal, climatic, regional geological and anthropogenic factors. The principles and methods of engineering and geological studies for the seismic microzonation of cities, the classification of soils by their seismic properties, the engineering and seismic geological typification of territories and the method for compiling the seismic magnitude increment map have been developed. The basic principles of the theory of interaction between engineering and economic activities of man and the geological environment in urban areas are determined. The general specific laws of anthropogenic impacts on the geological environment and its individual components are revealed. A model of interaction between the "City and geological environment" system, which is the methodological basis for predicting anthropogenic changes in the geological environment, has been developed, and the basic principles and methodological techniques of engineering and geological research at various stages of urban planning have been developed.
M.Sh. Shermatov (1990) on the example of the Middle Tien Shan, studied the patterns of formation of engineering-geological conditions of epiplatform orogenic territories. General and specific patterns of formation and spatial variability of geotechnical conditions are identified. The main factors determining the manifestation and development of geological processes and phenomena, their dependence on altitudinal zonality are established. The principles and content of engineering geological geography of regionalization have been developed taking into account the complexity and regularities of the spatial variability of engineering geological conditions, a system of taxonomic units of engineering geological zoning has been proposed. A forecast typological map of seismic intensity changes and a regional scale of seismic magnitude increment were compiled. Developed the guidelines for conducting engineering-geological studies for detailed seismic zoning.
The problems of research and calculation of seismic risk in Uzbekistan were the subject of N.G. Mavlyanova is quite fully reflected in a number of her publications before and after defending a doctoral dissertation (1986-2015). She has developed a methodology for researching seismic risk factors, describing the information base on seismic hazard. The dynamics of changes in seismic hazard and seismic risk factors within the urbanized areas of seismically active regions of Uzbekistan are determined. The models of residential buildings are presented and vulnerability is calculated by models of residential buildings. The calculation of engineering seismic risk and the assessment of individual and social seismic risk: a database has been created to assess seismic risk factors and their changes within the urbanized areas of seismically active regions of Uzbekistan.
During the period of independence of Uzbekistan, the laboratory staff conducted a complex of studies, but the study of the degree of change in the engineering-geological conditions of seismically active regions of the republic, in particular, investigated the reference sites of the distribution of loess territories results, which are reflected in the monograph by Kh.L. Rakhmatullaev and others. “Loss rocks of Uzbekistan”, ed. in NIIMR 2010., 267b.
While 2003-2007 The geoecological and seismoecological conditions of the urbanized territories of Uzbekistan are studied, the results of which are reflected in the monograph by L.M. Khudaibergenova, K.Sh.Nurmuyaamedova, MAAuyuyevonon et al. “Geoecology and seismoecology of cities of Uzbekistan”, published by Iktisodiet: Tashkent, 2014, 309s.
 The patterns of formation and change of engineering-geological conditions and seismic risk factors in the urbanized territories of Uzbekistan are investigated. Where regional and local laws and factors of formation and change of engineering-geological conditions and seismic cascade factors in the urbanized territories of Uzbekistan are revealed, the results of which are reflected in the monographs of A.M. Hudaybergenov, K.Sh. “Regularities of formation and change of engineering-geological conditions and seismic risk factors in the urbanized territories of Uzbekistan” published by the Navruz Publishing House: Tashkent 2015, 335p.
From 2012 to 2016 studied the patterns of formation of natural and man-made changes in the geological environment as the basis of seismic risk. The main goal of the research is to create a methodological basis for forecasting the development of natural and man-made changes in the geological environment and its regulation to assess the current state of engineering geodynamics of the area and complex geological risk as the main factor causing the seismic risk in urban areas. The features of the formation of natural and man-made changes in the geological environment with the purpose of assessing the current state and forecast of engineering geodynamics of the area and seismic risk in the zones of Uzbekistan are revealed. Principles and criteria have been developed for assessing territories according to the degree of complexity of engineering and geodynamic conditions, the danger of damaging processes and the degree of infestation; a methodology has been developed for long-term forecasting of the development of natural and man-made changes in the geological environment and its regulation. Compiled geological risk maps of the territory of cities and industrial centers in the zones of Uzbekistan have been compiled. A set of recommendations has been developed for the rational use and protection of the geological environment, the reduction of damaging formative exogenous geological processes and phenomena, and the seismic risk on the territory of cities and industrial centers in the zones of Uzbekistan. The results of the research are reflected in the monograph by M.A.Tuychieva, N.M. Dzhuraeva and others. “Regularities in the formation of natural and man-made changes in the heliological environment as the basis of seismic risk”, Pubruck Navruz: Tashkent 2016, 325p.
