摘　　要：软土基坑水泥搅拌桩-土钉组合支护结构比土钉墙具有更大的优势,本文介绍了其工作机理,提出软土基坑水泥搅拌桩-土钉组合支护结构的整体稳定计算方法,并结合工程实例对水泥搅拌桩的合理长度和宽度进行了讨论。The composite retaining wall combined cement mixing pile with soil nailing has greater advantage than soil nailing wall. The composite retaining wall mechanism is instroduced,and the whole stability calculation method is proposed in the article. A discussion on rational length and width of cement mixing pile is studied in a soft clay foundation excavation example.
