Abstract

Abstract

Compaction degree is an important factor affecting the stability of the fill slope. In order to analyze the stability of the fill slope under different compaction degree, the working conditions of the fill slope under different compaction degree were designed, and the constitutive relationship model of the compacted soil was analyzed and established. Based on the finite element strength reduction theory, the deformation and failure trend were analyzed and the ultimate shear strength was determined. Using the Bishop method to calculate the forces on both sides of the soil strip, without considering the lateral deformation of the soil, the stability coefficient of the slope and the settlement deformation value caused by the external stress of the fill soil were calculated. Based on the calculation results, stability protection measures for the fill slope were proposed. The results show that the proposed analysis method can accurately analyze the deformation of fill slopes, effectively reduce stability analysis errors, and apply it to the stability analysis of actual fill slopes, which has practical application significance.
