Estimation of soil degradation under prolonged cyclic loading, simulating storm wave effects on a structure.

Integrated assessment of possible soil degradation under cyclic loading caused by storm waves includes the analysis of hydrological data; the calculation of anticipated parameters of storm-wave amplitude-frequency spectrum and the corresponding shear forces; strength prediction based on experiments performed using the calculated wave parameters and loads; and the final analysis of soil behavior with regard to the time distribution of waves with different heights during the accepted storm activity period. The soil foundation stability was estimated for a site in the North Caspian shelf. [ABSTRACT FROM AUTHOR]
