Annotation:

The paper presents the results of the calculation of gravity retaining walls of various types (reinforced concrete corner with a front console and massive reinforced concrete) without taking into account and taking into account soil friction when calculating operational static and seismic loads. Calculations were carried out for given dimensions of retaining walls and characteristics of backfill soils from sandy soils on weak clay base soils. Based on this, a dependence was obtained to determine the angle of friction of the soil on the rear surface of the wall under seismic loading of various intensities. The paper emphasizes that the obtained calculation results are in good agreement with research data on the behavior of sandy soils under dynamic wave loads.
