COMPLEXING OF GEOPHYSICAL METHODS FOR SOLVING ENGINEERING AND GEOLOGICAL PROBLEMS (ON THE EXAMPLE OF PISTALITAU FOOTHILLS)

Abstract

Today, the need for new sites for the construction of modern facilities is growing every year as a result of the rapid development of “construction of buildings and industrial facilities” in the new Uzbekistan. New, sparsely populated and ecologically clean territories are selected for industrial facilities, and the selected territories are studied in detail using modern geophysical methods to improve the quality of construction and increase the level of durability of buildings and structures. The following article is devoted to the study of the geological structure, as well as geophysical properties using shallow geophysics in the design and construction of buildings and industrial structures that will be built in the foothills of the Pistalitau. The study used engineering and geophysical methods, such as seismic tomography - the method of refracted waves and electrical sounding - vertical electrical sounding. As a result of geophysical work, the seismic properties of the medium were determined from the velocities of propagation of primary and shear waves by the method of refracted waves, as well as the thickness of Quaternary deposits and the specific electrical resistivity of rocks were determined by the method of vertical electrical sounding. Based on the results of the study, the authors have constructed velocity models of the environment, maps of reflecting boundaries, and geoelectric sections. Geophysical data obtained as a result of the above works - shear wave velocity, the density of soil layers, groundwater level - are used as important parameters in the design of buildings and industrial structures in the foothills of Pistalitau.
