挡土墙主动土压力分布研究

该文基于极限平衡理论,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;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。

Study on Distribution of Active Earth Pressure on Retaining Wall

Based on the soil critical equilibrium theory,the article uses the thin-layer method to discuss the distribution of earth pressure on retaining wall under the different working conditions that there are no wall-back excavation backfilling and excavation backfilling,and deduces the theoretical formulas of active earth pressure strength and the active earth pressure coefficient.The results show that the wall-back active earth pressure is linearly distributed along the wall height under the condition of no wal...
