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.
In the earth pressure calculation of retaining wall, considering the fact that the actual rupture plane of the wall behind the earth is a surface and the internal friction angle obtained by the laboratory is too large, the theory formula of nonlinear earth pressure based on the horizontal microdroplet method is improved. A combined calculation method of static earth pressure and active earth pressure is presented.The results show that the calculated result is in good agreement with the measured data and basically includes the experimental data, which shows that the proposed new method is reasonable.
