Abstract
This report presents the results of the authors' research on the development of a method for assessing the earthquake-resistant steepness of slope structures and experimental verification of the main provisions of the method. The internal and external factors that directly affect the stability of the oscillating slope are given. As an internal factor, the strength and deformation parameters of soil in the body of the slope are considered, depending on the type of soil, its granulometric and mineralogical state, the state of density-humidity, etc. The external factors are the slope loading and the dynamic effect (amplitude, frequency, period, duration). The stability of the slope steepness is also affected by the height of the slope, the method of its construction, and the soil liquefaction that occurs under the influence of concussions. An account for all these factors allowed the authors to propose a theoretical method for assessing the earthquake-resistant steepness of slope structures. Comparisons of the data counting with the results of experimental studies showed good convergence.
