摘要
针对大面积仓储软基处理的难题,综合分析多种地基处理方法,在场地条件复杂的情况下,采用强夯联合CFG桩复合地基对大面积仓储软土地基进行加固处理,解决软土沉降、承载力不足等问题,论述强夯联合CFG桩复合地基的设计计算方法、施工工艺、成桩试验和检测结果。通过承载力和沉降验算论证了强夯联合CFG桩复合地基能够满足规范要求,同时针对沉降计算结果提出了通过变形协调设计来优化地基处理方案。
Based on the problem of large storage in soft ground, analysising various ground treatment methods comprehensively,using dynamic compaction joint CFG pile to reinforce large area warehouse soft soil foundation under the condition of complex field, this paper solves the problems such as lack of soft soil settlement and bearing capacity and discusses the design calculation method construction technology,pile forming,test and detection results of CFG pile composite foundation.
