管桩桩基工程中应力释放孔的设计及应用

摘要

分析了管桩在施工过程中应力释放的过程以及对土体的破坏机理,介绍一工程实例,采用施工应力释放孔措施解决挤土效应并获得成功,对管桩设计及施工有较好的参考价值。%The article analyzes the stress releasing process of the pipe pile in construction and its damage mechanism for soil body. Taking the some engineering ease as an example, it applies the construction stress releasing hole to solve the compaction effect and achieves the great success, which has great referring value for pipe pile design and construction
