摘要: 通过对挡土墙土压力非线性分析方法的研究,推导出了衡重式挡土墙土压力计算的数解公式,并编制了相应的计算程序,一般的直线型墙背挡土墙和折线型墙背挡土墙土压力计算均可作为本文计算公式的特例。通过对一折线型墙背重力式挡土墙的土压力计算与实测结果的比较表明,由本文公式所得的解与实测结果很接近。

Abstract: A theoretical formula about the non-linear distribution of active pressure acting on the back of balance weight retaining wall has been deduced by researching the houizontal layer analysis.In fact,the general retaining wall and the broken segmental back wall can be looked as a special case of this formula.According to this formula, a general program for calculating non-linear earth pressure has been developed. By comparing the theoretical solution gained from the program with the result of testing a weight retaining wall,it indicates that the theoretical solution is practicable in calculating the active earth pressure on the back of retaining wall.
