摘要:
根据水泥土桩桩-土接触面载荷传递模型试验、水泥土桩与灌注桩承载力的现场足尺对比试验和有限元分析,对水泥土桩载荷传递机理和破坏机理进行了分析,对水泥土桩复合地基载荷试验承压板-桩-土相互作用进行了研究,进一步分析了复合地基载荷试验方法对单桩进行检验的局限性,辨证分析了褥垫层对水泥土桩复合地基承载力确定的影响,不能简单地认为垫层对提高复合地基承载力和减少沉降是有利的.本文还对单桩破坏模式及承载力的评定方法提出了建议.
Abstract:
Through the model test, bearing capacity test in-situ of soil-cement mixing pile and cast-in-place pile and finite-element method, the load transfer and failure mechanism of the soil-cement mixing pile is studied. The loading plate-pile-soil interaction of the loading plate test of soil-cement mixing pile composite is also studied. The effect of the cushion on the bearing capacity of soil-cement mixing pile composite is analyzed and the results show that the cushion can not be simply regarded as favorable to enhance the bearing capacity and reduce the settlement of soil-cement mixing pile composite. Finally, the method to evaluate the bearing capacity of soil-cement mixing pile and its mode of failure is suggested.
