| 摘 要： | 基于水平层分析法的思想,采用薄层微元法,推导了考虑挡墙墙高、墙背倾角、填料面仰角、均布超载、填料重度、填料摩擦角、填料与墙背粘结力和摩擦角(外摩擦角)等条件下的粘性土被动土压力公式的解析解,采用图解法给出了临界破裂角的显式解答.并分析了这些因素对被动土压力临界破裂角、被动土压力强度分布、土压力合力大小和作用点位置的影响...

| Abstract: | Based on the thought of horizontal layer analysis,thin-layer micro-element method was suggested to deduce the passive earth pressure formula of cohesive soil considering the height of retaining wall,batter angle of wall back,elevation angle of filler,equispaced overloading,gravity and internal friction angle of filler,cohesion and external friction angle between filler and wall back.Explicit solution of critical rupture angle was obtained by graphic method.The effects of these parameters on critical rupture... |
