水泥土桩和水泥砂浆土桩的破坏与承载力研究

Study failure and the bearing capacity of cement-soil and cement mortar soil model piles

以劲性水泥土桩、劲性水泥砂浆土桩、加筋劲性水泥砂浆土桩三种形式的桩为研究对象,在试验室分别制作了三种形式模型桩,并依据其极限承载力试验,对比分析了三种模型桩的破坏形态与Q—S曲线以及竖向极限承载力,提出了三种模型桩的异同点以及变化规律,为工程应用提供参考。

Based on the three forms piles of strength cement-soil,strength cement mortar soil,reinforced cement mortar soil as the research object,it respectively fabricates three kinds of model pile in the tab,and follows its ultimate bearing capacity test,the damage form,Q—S curve and vertical ultimate bearing capacity of pile of comparison and analysis for three kinds of model pile,and puts forward three kinds of model of the similarities and differences as well as the changing law,provide a reference for engineering application.
