复合土钉墙在某人防深基坑工程中的应用

The application of composite soil nailing wall in a civil engineering deep foundation pit

以某人防深基坑工程为例,通过对基坑支护设计与施工的探讨,选择了深层水泥土搅拌桩+土钉墙复合支护方案,并对施工组织设计作了阐述,指出复合土钉墙在开挖深度不大、相邻建筑对沉降与位移要求低的基坑支护中,既可保证施工安全,又可降低施工成本。

Taking a civil engineering deep foundation pit engineering as example,through the discussion on foundation pit support and construc-tion,selected the deep cement soil mixing pile ＋ soil nailing wall composite support scheme,and elaborated the construction organization,point-ed out that the composite soil nailing wall not only could guarantee the construction safety,but also could reduce the construction cost in the foun-dation pit support of small excavation depth,loe requirements of adjacent buildings to settlement and displacement.
