摘要
花岗岩残积砂质粘性土具有特殊的工程特性,作为地基持力层,其承载力和变形指标的确定存在不小难度。本文通过对厦门地区的花岗岩残积砂质粘性土现场载荷试验、旁压试验与标准贯入试验成果进行分析,并就承载力和变形模量进行了探讨,提出了确定花岗岩残积砂质粘性土地基土承载力和变形模量的方法。
As bearing layer of foundation, with special construction properties, the value of bearing capacity and deformation index of granite residual sandy sticky clay is difficult to decide. Through analysis of plate loading test, pressuremeter test and standard penetrating test of granite residual sandy sticky clay in Xiamen city, this paper discusses its bearing capacity and deformation prop- erty, provides the method for obtaining the value of its bearing capacity and deformation modulus.
