摘　　要：河南信息南广场基坑支护工程,分别采用了桩锚支护、微型桩+预应力锚杆复合土钉墙支护和微型桩复合土钉墙支护体系,具体介绍了护坡桩、预应力锚索、微型桩、预应力锚杆、土钉墙、花管桩设计施工方案以及基坑监测变形异常后采用的应急处理方案,技术成果为类似工程的设计施工提供参考。In a foundation pit supporting engineering of Zhenzhou, the pile anchor support, micro pile ＋ pre stressed anchor composite soil nailing wall support and micro pile composite soil nailing wall support systems are a dopted respectively. The paper introduces the design and construction schemes of slope retaining pile, pro stressed anchor cable, micro pile, pre stressed anchor, soil nailing wall and perforated pipe pile in detail, as well as the e mergency response plan adopted for the abnormity in foundation pit deformation monitoring, this technical achieve ment provides reference for the design and construction of similar projects.
