| 中文摘要:基于极限平衡理论，利用单元分层法分别讨论了墙后无开挖回填和有开挖回填不同工况条件下的挡土墙土压力分布形式，推导出不同工况条件下的主动土压力强度及主动土压力系数理论公式。结果表明，墙后无开挖回填工况条件下墙背主动土压力沿墙高成线性分布；[JP2]墙后有开挖回填工况条件下墙背土压力沿墙高成非线性分布。 |

| Abstract:Based on the soil critical equilibrium theory, the paper discussed the distribution of earth pressure on retaining wall under the working conditions with or without excavation and backfilling between the wall and ground by thin layer method, deducted the formulas of active earth pressure strength and coefficient of active earth pressure. The results show that the relation between the earth pressure strength and the depth of wall is linear under the working condition with excavation and backfilling and nonlinear under the working condition without excavation and backfilling between the wall and ground. |
