摘　　要：深厚淤泥层具有高压缩性、低抗剪强度及高含水量等特点,在复杂地质条件下进行深基坑开挖时,极易引发变形和滑移。本文针对复杂地质条件下深厚淤泥层基坑工程,探讨了水泥土墙、支护桩+锚索+土钉+被动区加固、支护桩+被动区加固等多种支护方法,系统分析了各方法的施工过程,并通过实际工程验证了其技术可行性。The deep sludge layer has the characteristics of high compressibility,low shear strength and high water content.It is easy to cause deformation and slip when deep foundation pit is excavated under complex geological conditions.For foundation pit engineering under complex geological conditions,this paper discusses a variety of support methods such as cement earth wall,supporting pile+anchor cable+soil nail+passive area reinforcement,supporting pile+mixing pile+passive area reinforcement,systematically analyzes the construction process of each method,and verifies its technical feasibility through practical projects.
