| 摘 要： | 在挡土墙土压力计算中,考虑墙后土实际破裂面为一曲面以及实验室得到的内摩擦角偏大的影响,对基于水平微元体法的非线性土压力理论公式进行改进,提出一种静止土压力与极限主动土压力的组合计算法.研究结果表明,组合计算结果与试验实测数据吻合较好,并且基本上把试验数据包括在内,说明提出的新方法是合理的.

| Abstract: | It was taken into consideration for evaluation of soil pressure on retaining walls that the actual fracture surface of the soil behind walls was a curved one and the inner frictional angle obtained in lab was on the low side,so that the theoretical evaluation formula of nonlinear soil pressure,which was set up on the basis of horizontal elemental volume approach,was modified,and further,a combined evaluation method for static soil pressure and limiting active soil pressure was presented.It was shown by inve... |
