METHODS OF CONSIDERATION FOR ANOMALOUS CHANGES IN THE PHYSICAL ANDMECHANICAL PROPERTIES OF SOILS DURING EARTHQUAKES IN THE AREAS OFCONSTRUCTION WORK

Abstract

Solved issues visual inspection of the construction site and identification of possible environmental
hazards (landslides, landslides, avalanches, etc.) study of lithological composition of soil, determination of main
dividing boundaries of layers, construction of seismic sections at depth, study of seismic features of stratified
environment, study of geological-tectonic conditions of construction site by geophysical (seismic, electric,
magnetometric and gravimetric) methods, geophysical data To build a 3D model, to determine the number of
points (based on the CEC-64 scale) in the zone on the basis of seismic zoning and microseismic zoning maps of
the construction site, to determine the mechanical properties of the soil in the construction site, modern
ecological assessment of safety conditions and design of the project taking into account the construction norms.
Keywords: seismic sections, geological structure of layers, lithological composition of soil, geophysical
methods (seismic, electrical, magnetometric and gravimetric), 3D model of layers, seismic zoning and
microseismic zoning maps, construction norms
