| 摘 要： | 利用2002年在杭州湾内的潮流槽脊系和湾口浅滩上进行钻探取得的样品,对杭州湾浅层粘性土的物理力学指标进行了统计和分析,结果表明:杭州湾浅层粘性土是一种含水率较高、孔隙比较大、高压缩性、低强度的粘性土,其物理指标和力学指标变异性差别大,特定指标间存在较好的相关性,力学指标和物理指标间有一定的回归性,回归方程形式一致。

| Abstract: | Clay in the Hangzhouwan Bay is a kind of cohesive soil with high water content,looseness and high compressibility.According to the data of soil test in the Hangzhouwan Bay,the paper statistically analyzes the variability differences,correlation and regression between physical and mechanical indexes.The results discover that variability differences in physical indexes are less than those in mechanical indexes;Mechanical indexes,including coefficient of compressibility,cohesion and friction angle,correspond with relevant physical indexes respectively and can be expressed with their respective regression equations.The regression equation forms of CL and CH are similar,but the data calculated by CL regression equation are more close to the data of soil test than those calculated by CH's. |
