| 摘 要： | 基于库仑理论的平面滑裂面假设,考虑滑裂面上填土凝聚力及填土与挡土墙墙背接触面上粘着力,对粘性土主动土压力的库仑精确解算法进行了改进。改进的库仑精确解算法对超载的处理及裂缝深度的计算简单;对按不考虑填土表面出现裂缝的情况,只需取Z0=0,与按出现裂缝情况完全相同。公式计算简便,精度可靠,易于推广应用。

| Abstract: | Based on sliding plane hypothesis of Coulumb earth pressure theory, Coulumb accurate solution of active earth pressure to cohesive soil was improved which considered the cohesion force on sliding surface and the adhesive force on interface of retaining wall. The improved method is simple to handle load on soil surface and calculate crack depth. Only taking Z0 to be the equal of zero, the calculation formula without considering crack on soil surface is the same as those considering crack completely. The formula is reliable and convenient. It is easy to popularize and apply for projects. |
