对平移模式下的刚性挡土墙和滑裂面间的楔形土体处于被动极限平衡状态的应力进行分析,考虑墙面和滑裂面之间土体水平力平衡,运用土拱效应原理推导出被动土压力系数和滑裂面水平倾角。并根据水平单元土体的静力平衡条件建立平衡方程,提出被动土压力分布、土压力合力及其作用位置的公式。将公式计算结果与试验结果以及库仑、朗肯理论所得结果进行比较,结果表明,与试验结果接近,验证了所得计算方法的合理性。
The stress of the passive limit equilibrium between the rigid retaining wall under sliding mode and the wedge-shaped soil between the sliding surfaces is analyzed. The balance of soil horizontal force between the wall surface and the sliding surface is considered, and the soil arching effect principle is deduced Passive earth pressure coefficient and slip plane dip. According to the static equilibrium condition of horizontal soil, the equilibrium equation is established and the formula of passive earth pressure distribution, earth pressure force and its action position are proposed. Comparing the calculated results with the experimental results and the results of Coulomb and Rankine theory, the results show that the calculated results are close to the experimental results, which verify the rationality of the calculation method.
