花岗岩残积土物理力学指标的概型分布检验

Probability Type Testing of the Distribution on the Granite Eluvial Soil Mechanical Parameters

根据我国东南沿海地区花岗岩残积土的土工试验资料 ,用 3～ 4种检验方法对含水量、重度、孔隙比、塑性指数、液性指数、压缩系数、内摩擦角、粘聚力等 8项试验指标进行了概型分布检验 ,得出各项指标大都可用对数正态或正态分布函数拟合的结论 。

Based on the test data on granite eluvial soil on the South East coastal area in China, 3 to 4 test methods are used on the probability distribution test in eight parameters, water content, bulk density, void ration, plastic index, liquid index, compressibility coefficient, angle of internal friction and adhesion. The conclusions are that all above the eight parameters can be applied to the function of the normal distribution and the logarithmic normal distribution. The data is provided for reliability design on the foundations.
