基于杭州泻湖相软土层土性指标试验数据，研究了其物理力学指标沿深度的变化情况，结果表明：杭州泻湖相软土层物理指标沿深度没有明显变化趋势，变形和强度参数存在明显的深度变化趋势，在统计时需对数据进行回归分析和趋势性分析。分析了杭州泻湖相软土物理力学指标的变化范围、变异性、指标之间的相互关系以及指标的概率分布模型，得到了杭州泻湖相软土物理指标与变形指标、强度指标之间的统计关系经验公式，分析表明杭州泻湖相软土物理指标服从正态分布、变形指标服从对数正态分布、强度指标的内摩擦角服从正态分布、粘聚力同时服从正态分布和对数正态分布，但对数正态分布更容易被接受。

Based on the testing data of soil indices of lagoon facies soft soil layer in Hangzhou, the change of the physical and mechanical indices with the depth is studied. The result shows that the physical indices thereof has no significant change with the depth; however the deformation and strength parameters has an obvious trend of changing with depth. All of these data are required to be carried out regression and tendency analysis in statistical estimation. Then the change confines, variability, correlation between indices, and probability distribution model of the indices are analyzed to obtain the empirical formulas of statistical relationship between the physical index, deformation index, strength index. The analysis results show that the physical index is in deference to normal distribution, the deformation index to lognormal distribution, the internal friction angle of the strength index to normal distribution, and the cohesion to both normal and lognormal distributions, but lognormal distribution can be accepted more easily.
