  • To analyze the internal stability of reinforced retaining wall under earthquake loads, according to the characteristics of layered filling, stratified compaction and horizontal layered arrangement of reinforcement strip, by selecting the logarithmic spiral as the integral slip surface, an analysis method for the internal stability of reinforcement retaining wall under earthquake loads is set up based on the horizontal slice method. The formula for calculating the tensile strength of bar strip and anchorage length are derived. The maximum tensile of bar strip is regarded as the linear programming optimal solution. By using MATALAB software a program is written to obtain the maximum tension of the bar strip and the corresponding most dangerous sliding surface. The proposed method is applied in an engineering example, and the tension value of the bar strip is calculated and compared with that of the finite element ABAQUS software. The rationality of the method is verified, and it is indicated that the proposed method is safe and reliable.
