摘要:
假定滑裂面为通过墙踵的折线,将水平层分析法推广到填土分层的挡土墙的土压力计算中,合理地解释了墙背不光滑时主动土压力分布的非线性特点.在平移模式下,水平层分析方法可得到和库仑理论基本一致的主动土压力合力,但是得到的倾覆力矩大于按库仑理论得到的结果,而且合力作用点明显高于库仑理论的结果,这说明库伦理论高估了平移模式下挡土墙的抗倾覆稳定性.另外,理论分析表明墙后上软下硬的填土方案要优于上硬下软的填土方案.
Abstract:
Assuming that the slip fracture surface is a polyline through the wall heel, the horizontal layer analysis method is generalized to the calculation of earth pressure of the retaining wall filled with layered soil, which reasonably explains the nonlinear characteristics of the active earth pressure distribution when the wall back is not smooth. In the translation mode, the horizontal layer analysis method can obtain the active earth pressure resultant force that is basically the same as Coulomb’s theory, but the overturning moment obtained is greater than the result obtained according to Coulomb theory, and the resultant force point is significantly higher than the result of Coulomb theory, which indicates that Coulomb theory overestimates the overturning stability of retaining walls in translation mode. In addition, the theoretical analysis shows that the upper and lower hard filling scheme behind the wall is better than the upper hard and soft bottom filling scheme.
