摘要
根据对挤密桩和CFG桩作用机理的分析,详细论述了在湿陷性黄土地区采用先挤密地基土,后施工CFG桩的多桩型复合地基处理技术。结合工程实例,详细介绍了挤密桩和CFG桩复合地基的设计方法与施工工艺,并通过复合地基检测结果的评价,表明了该方法具有降低成本、缩短工期、技术先进的优点,可在湿陷性黄土地区推广应用。
According to analysis of action mechanism of compaction pile and CFG pile,authors elaborates the multi-pile composite subgrade technique which compacts the foundation soil first and then constructs the CFG pile.Based on practical project,design method and construction procedures are described in detail for compaction pile and CFG pile in collapsible loess area.Through the evaluation of composite subgrade detection results,it indicates that the mentioned method has the advantages of cost reduction,construct period shortening and technology advanced.It can be used in collapsible loess area extensively.
