On the dependence of soil friction on the intensity of pressure in the calculations of a retaining wall for a seismic load
Issue: #1-2023

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.

The article outlines the most important aspects and summarizes the main results of the calcula-tion and design of a gravitational retaining wall reinforced concrete corner with a front con-sole and massive reinforced concrete on the seismic load. A comparative analysis of the calcu-lations for the operational case with static and seismic load for a wide range of input data is given. It is emphasized that during the design of the base of the retaining wall it is not al-lowed to liquefaction the sandy soils of the backfill and cushion at its base, which will lead to a catastrophic loss of the bearing capacity of the base soils and the stability of the retaining wall. To increase the stability of the structure of sandy soils, the liquefaction process should be applied by effective vibrodynamic methods of their compaction, developed by the author.
