摘　　要：位于复杂地层中的某基坑工程 ,开挖深度达 9 5m ,采用土钉墙作为基坑支护结构 ,当基坑开挖到淤泥土层时 ,其中一侧土钉墙发生塌滑 ,另一侧土钉墙也产生较大的水平位移。在分析场地工程地质条件、土钉施工及周围环境的基础上 ,研究了土钉墙产生塌滑的原因 ,并根据现场施工情况 ,提出了切实可行的土钉墙基坑加固设计方法 ,做到既安全 。Soil nailed walls are used as excavation supports for certain deep foundation pits located in complicated stratum. When the excavation work reaches to the muddy layer, soil nailed wall on one side collapses and slides, while the wall on another side presents relatively great horizontal deformation. On the basis of analysing the geological condition of the field, soil nailed wall construction and the situation, the causes of collapse and slide are studied, and a feasible design method for reinforcing soil nailed walls is proposed.
