Soil Mechanics and Foundation Engineering Aims and scope

In this study, the fine particle elimination method was used, and a series of triaxial consolidated drained shear tests was conducted to study the influence of the initial relative density on the drained strength properties of eroded soil. The results of the triaxial consolidated drained shear tests showed that under the same confining pressure, when the loss rate of fine particles was held constant, the soil samples with large initial relative densities exhibited higher drained failure strengths; the influence of the initial relative density on the degree of reduction of the drained failure strength was complex; when the loss rate of fine particles was held constant, the drained internal friction angle increased with increasing initial relative density; and when the loss rate of fine particles was constant, the degree of reduction of the drained internal friction angle was similar for different initial relative densities.
