摘要
应用极限平衡理论和对岩土材料的刚塑性假定来分析挡土墙上土压力分布是工程中常用的方法,通过提取滑动面上的三角形单元,以及与之相关的竖直微条和水平微条,加之一些近似假定,建立三者的静力平衡方程。方程求解结果和朗肯主动土压力和被动土压力一致。
It is a common engineering method to analyse distributing of earth pressure on retaining wall by applying limit equilibrium theory and assume of rigid plasticity of rock and earth material. This paper establishes static equilibrium equation by distilling a triangle cell of sliding surface and upright and level tiny bars ,together with several approximate assumes. The result of the equation is consistent with Rankine＇s initiative and passive earth pressure.
