| 摘 要： | 基于极限平衡法，通过严密的数学推导和理论分析提出了适合任意土质、任意墙背倾角、任意单一斜度填料面的加筋土挡墙墙背主动士压力非线性分布的通用表达式，得出了加筋土挡墙土压力分布和合力作用点的高度计算公式。通过泥质红砂岩土石混合填料加筋土挡墙工程现场实测土压力值进行了对比分析，结果表明：上述计算方法合理，计算值与实际相符，拓宽了朗肯土压力理论库仑土压力理论应用范围，可直接应用于工程设计。

| Abstract: | Based on limit equilibrium method,general formulas were deduced for predicting the nonlinear distributed active earth pressure acting on back of reinforced retaining wall with any backfill,any inclination of back,as well as any single slope of filling surface.Expressions of resultant force and height of action point of the resultant force were obtained.Comparative analysis was conducted between measured values and calculated values of active earth pressure of reinforced retaining wall with shaly red sand st... |
