摘要: 复合桩地基的承载力是由桩和桩间土共同分担,旨在充分发挥和利用地基土的承载力潜力,通过串珠状桩体来实现对桩间土的加固和挤密,用多种试验检验方法对复合地基进行全面分析探讨,阐明了钻孔夯扩挤密复合桩地基可以有效地解决天然地基承载力不能满足高层建筑物设计要求的问题。Abstract: The composite foundation is composed of pile and soil in order to bring latent capacity of soil into full play by reinforcing the soil with string-pearl shape.According to many insitu tests and analyses,the result show that the composite foundation with drilling ram-expanded piles could be applied to high-rise building effectively and successfully.
