Abstract

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