挤扩多盘桩土体极限承载力影响因素的研究

Research on the Factors Affecting the Ultimate Bearing Capacity of the Soil Around of the Push-extend Multi-under-reamed Pile

根据挤扩多盘桩桩土效应及土体极限承载力的理论分析和试验研究的成果,对挤扩多盘桩土体极限承载力的多种影响因素进行了定性或定量的分析,为进一步综合考虑各项因素进行挤扩多盘桩基础设计,提供了理论依据。

In the paper, according to the theory analysis and test results of researching on the effect of pile and soil work together and the failure principle of the soil of the push - extend multi- under- reamed pile, it is analysed qualitatively and quantitatively that the influence factors affecting the ultimate bearing capacity of the soil around of the push - extend multi - under - reamed pile. The results of the paper put forward the theory basis for design the bearing capacity of the pile in the practical project.
