摘　　要：某工程紧邻建筑物,开挖基坑边壁直立,邻楼建筑物部位采用复合土钉支护模板墙方法进行支护;其他部位采用土钉支护模板墙技术进行支护。通过对关键施工环节进行控制,对边壁面平面度控制,对边壁位移进行控制,取得了良好的效果。A project is adjacent to existing upright, so the part adjacent to existing building building and the side walls of excavated foundation pit are is supported by compound soil nail supported formwork wall, while other parts are supported by soil nail supported formwork wall. Favorable construction effects are realized through successful controls of key construction steps, wall surface planeness and side wall displacement.
