摘要
SMW法是采用加劲性桩的围护结构。本文通过室内静力模型实验,得到了劲性桩围护结构侧向土压力随开挖过程的变化规律以及影响范围随开挖深度的变化规律:存在临界开挖深度,当开挖深度小于临界开挖深度时,侧土压力的影响范围随开挖深度的变化较快;当开挖深度大于临界开挖深度时,影响将变缓。
SMW method means using the retaining structure with stiffened piles. In this paper, the relationship between lateral pressure during the excavation process and influenced zone with the development of excavation depth are presented as the results of model test. It is considered that a critical depth is existed and the influenced zone changes rapidly when the excavation depth is less than the critical depth, otherwise,it changes slowly.
