On the change in the strength properties of quaternary deposits in the sides of the quarry under the influence of natural and climatic factors

Abstract

The features of changing the properties of quaternary deposits in the sides of the quarry under the influence of climatic factors during rainfall and drying of the soil as a result of drainage and evaporation of moisture are considered. Using the methods of seismodeformation monitoring based on the records of seismic signals and metric measurements of the displacement of the reference points on the edges of the side in the fault zone, the limits of the change in the hodographs and the rate of displacement of the soil during its moistening and drying are determined. The spread of hodographs in the range from 15 to 25% is essential for the development of erosion and requires control to prevent emergencies. These results indicate the natural self-organization of the destruction of rocks of the marginal part of the side of the quarry under the influence of seasonal natural and climatic factors due to changes in the strength of the near-surface layers of the soil.
