摘要
以上海某新建高档服装服饰生产基地项目的基坑工程为背景,对型钢水泥土搅拌墙支护方案的设计及有限元数值分析情况进行了介绍,并就有关技术要求进行了阐述。实践证明,在软土地区采用型钢水泥土搅拌墙结合内支撑系统进行深、大基坑工程施工是可行的。总结的经验可为类似基坑工程的实践提供有益的借鉴和参考。
Taking the foundation pit project of a new high-grade garment&accessories production base in Shanghai as the background,the design and finite element numerical analysis of the support scheme of section steel cement soil mixing wall are introduced,and the relevant technical requirements are expounded.The practice shows that it is feasible to construct deep and large foundation pit in soft soil area using section steel cement soil mixing wall combined with internal support system.The summarized experience can provide useful reference for the practice of similar foundation pit engineering.
