RETRACTED: Formation conditions and parameters of mini-landslides on agricultural slope landscapes

Abstract

The paper investigated the stability of agricultural land slopes to mini-shear landslides on the basis of a numerical assessment of the influence of soil parameters in the Volga-Vyatka region of Russia on its frictional properties. It has been established that at a moisture content of 0.30 ± 0.04 m3/m3 of gray forest soil and 0.22 ± 0.04 m3/m3 of soddy-podzolic soil, the contribution of soil stickiness to the soil friction coefficient was the most significant, which was due both to the aggregation of soil particles and to the destruction of soil capillaries, and corresponded to the lower limit of soil plasticity. On the basis of the ratio proposed in the paper, a numerical assessment of the ratio of the power and length of the landslide along the slope for different slope angles was carried out, the results of which correspond to real landslide processes on natural and artificial slopes of agricultural land.
