摘要
通过分析土体与水泥土搅拌桩挡墙之间的相互作用 ,提出一种计算其水平位移的近似方法 .在墙宽与墙高之比较小时 ,视其为刚体 ,并用“m”法确定墙两侧土体的弹簧刚度 ,同时考虑墙重与墙底土的抗剪和抗倾覆作用 .利用该方法 ,探讨了水平位移与开挖深度的关系 ,同时可得到墙两侧土体的屈服范围以及所受的实际土压力 。
An approximate method to compute the horizontal displacement of cement-soil retaining wall is presented,by analyzing the interaction between soil mass and the wall.The wall can be regarded as a rigid body if the ratio of its width to height is very small.The stiffness of soil spring is determined by “ m ” method,and the effect of shearing and overturning resistance of the wall weight and the soil below the wall is taken into account at the same time in this paper.By this method,the relation between the horizontal displacement and pit depth is discussed,and the yield scope of soil and the real soil pressure are simultaneously obtained. Accordingly,its stability can be judged.
