软土地基条件下的基坑支护设计与施工的难度较大,单一水泥土墙或土钉墙支护方案存在着许多缺点,采用组合式支护可克服工程中的一些问题,但现阶段常用的组合式支护方案尚存在着一些缺点,本文从工程实际出发,并通过理论分析,阐述了在软土地区双层地基环境条件下的一种组合式支护方案,探讨了其设计依据与技术机理,供读者分析参考。
It is difficult to design and construct the foundation pit support under the condition of soft soil foundation. There are many shortcomings in the single cement soil wall or soil nailing wall support scheme. The use of modular support can overcome some problems in the project, but at this stage There are still some shortcomings in the commonly used combined support schemes. This article starts from the actual engineering and through theoretical analysis, describes a combined support scheme under the double-layered ground conditions in soft soil area, and discusses its design basis. And technical mechanism for readers to analyze reference.
