Basic Aspects of a Methodological Approach to Assessing the Seismic Resistance of Soils

A method is proposed for assessing the seismic resistance of soils, involving the analysis of seismic data (with soil conditions taken into account), the choice and specification of amplitude–frequency spectrum parameters, experimental studies of soil samples with specified cyclic load parameters, analysis of the dependence of soil behavior on the overload factor, and calculating the ultimate overload factor based on the comparison of accepted and ultimate effect levels. The paper gives the results of practical application of the developed approach to assessing the seismic resistance of a shelf area in the Northern Caspian Sea.
