摘　　要：地下空间的开发利用对基坑工程提出了更高要求,特别是深基坑的出现,由于工程不确定性和岩土工程复杂性,容易出现围护安全、变形稳定等问题,可采取组合支护结构形式,提高基坑稳定性。为此,文章以钻孔灌注桩咬合水泥土搅拌桩为例,简要分析组合桩作用机理,并结合实际工程案例,提出施工关键技术,从而为相关工作者提供参考。The development and utilization of underground space puts forward higher requirements for foundation pit engineering,especially the emergence of deep foundation pit.Due to the uncertainty of engineering and the complexity of geotechnical engineering,problems such as enclosure safety and deformation stability are prone to occur.Combined support structure can be adopted to improve the stability of foundation pit.For this reason,the paper takes bored pile occluding cement soil mixing pile as an example,briefly analyzes the action mechanism of composite pile,and puts forward the key construction technology combined with the actual project case,so as to provide reference for related workers.
