Abstract

This paper separately studies the friction strength and cementation strength of loess skeleton. The carbonate, silt and coarse particles serving as the skeleton structure in loess are separated, and carbonate samples, silt samples and skeleton particle samples are made. Then, direct shear tests are conducted on the samples. The variation laws of loess structure strength, friction strength and cementation strength with moisture content and vertical pressure are studied, and the degree of influence of friction strength and cementation strength on loess structure strength is explored. The results show that the structure strength, friction strength and cementation strength of loess all decrease with the increase of moisture content; with the increase of moisture content and vertical pressure, the proportion of carbonate and silt cementation strength in the structure strength of loess gradually decreases, while the proportion of friction strength in the structure strength of loess gradually increases.
