摘要

摘要: 为分析地震作用下加筋挡土墙的内部稳定性,根据加筋挡土墙分层填筑、分层压实及筋带水平布置特点,基于水平条分法,选用对数螺旋滑动面,建立地震作用下加筋挡土墙内部稳定性分析方法。推导出筋带拉力和所需锚固长度计算公式;筋带所受最大拉力为线性规划最优解,借助MATALAB软件编写程序,求得筋带所受最大拉力和对应的最危险滑动面。将提出的计算方法用于一工程实例,进行了筋带拉力计算,并用有限元软件ABAQUS进行了计算对比,验证提出计算方法的合理性,表明该计算方法安全、可靠。

Abstract: 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.
