SOIL CHARACTERISTICS AFFECTING THE SEISMIC EFFECT OF THE CONSTRUCTION SITE

Abstract

At estimating of seismic hazard, it is necessary to evaluate the local effect of earthquakes. The main factors that determine the parameters of surface vibrations during earthquakes include local effects associated with the response of the soil, the effects of surface topography and the topography of internal boundaries (heterogeneities, inclusions, sedimentary basins, etc.). At present, methods for reliable estimation of these effects have been developed in seismology. The probabilistic parameters of surface vibrations are needed to calculate the reaction spectra, dynamic stresses and deformations that cause the destruction of buildings, to assess the possibility of soil liquefaction. The article investigate the influence of local soil conditions on the seismicity of a construction site during an earthquake.
