绕基础转动模式下刚性挡土墙主动土压力的计算

采用考虑墙体位移模式和转角的土压力计算方法,能较好地反映挡土墙实际工作条件下的位移情况,并且能计算挡土墙任意转角下的主动土压力,避免了采用库仑主动土压力理论计算得到土压力偏小而使设计安全度降低的缺点。因此,本文提出的土压力计算方法对挡土墙的设计及验算有一定的参考价值。

The calculation of active soil pressure under rotary movement mode

The proposed methods of earth Pressure calculation considered the wall movement mode and rotating angles was developed in this paper. The active earth pressure under different rotating angles can be calculated,and lower results getting from using Coulomb＇ s solution that will lead to decrease the safety of the structures in design can be avoid .So, the proposed methods ean make the design of the retaining wall safer and more reasonable.
