摘要
本文就开挖边坡的长期稳定问题,对降雨和地下水位变化引起切坡内土的强度降低和应力状态的改变,进行了一系列的室内模拟试验。再现了由于地下水位上升切坡内土的应力路径变化过程,探讨了切坡破坏时的临界应力状态及土的强度参数。
Concerning with the long term stability problem, a series of laboratory simulation tests are conducted on the decrease of strength and the change of stress state of soil in cut slope induced by rainfall and by variation of groundwater level. Laboratory studies were also carried out to simulate the stress path in cut slope due to the rise of groundwater level. The critical stress state and strength parameter of soil during the failure of cut slope are discussed.
