PE管增强水泥土桩技术研究

STUDY ON PE PIPE REINFORCED CEMENT SOIL PILES TECHNOLOGY

分析水泥土桩在承载力贡献方面的不足,通过在上部增加约束克服不足,创造了PE管复合材料桩,并通过室内材料强度试验和现场复合地基载荷试验,验证了新桩型的可行性,初步提出了计算方法,为地基处理设计提供了参考。

This paper analyzes the contributions to the deficiency of cement-soil pile in bearing capacity, through constraints to overcome the deficiencies in the upper, created the PE pipe pile composite material, and through the strength of materials, laboratory test and in-situ composite foundation load test, verify the feasibility of the new pile type, put forward the calculation method, provides the reference for the foundation treatment design.
