Engineering seismic surveys in various soil conditions

Abstract

: The described study provides examples of the methods of refracted and reflected waves practical application for studying the near-surface section in various soil conditions. Examples of P-waves and S-waves at construction sites with soils of I-III categories in terms of seismic properties are considered. In each example, the bedrock conditions vary from 10 to 100 meters. The used devices and observation systems are described. As conclusions, specific tasks are listed, which are solved in practice using the study of soil strata by seismic methods. Conducting near surface seismic studies by the method of refracted waves in areas for the construction of buildings and structures for various purposes provides a significant amount of output data. This data used primarily for building velocity sections of the refracted waves and обра-studying the physical and mechanical characteristics, which makes it possible to assess the structural features of the near-surface section.
