天津软土物理力学性质的相关性研究
摘要:为探究天津软土各物理力学性质间的相关性.利用最小二乘法原理对土样的各测定指标进行统计。结果表明:初始孔隙比与压缩系数、压缩系数与含水量、含水量与孔隙比之间均有很好的相关性,可以用天然含水量估算软土的一些物理力学性质指标;液限与塑性指数的回归方程为:IP=0.43(ωL-10.8).与其它各地的塑性图相比有一定的差异性;同时,这些塑性图和卡氏塑性图中的IP=0.73(ωL-20)也存在一定差异,因此进行土的分类时应考虑土体的区域性。
Abstract:Method of least squares was used to determine the relevance among physical and mechanical properties of soft soil in Tianjin. The results showed that there were good relevance among initial void ratio, coefficient of compressibility and water content; natural water content and void ratio,so, water content can be used to estimate certain physical and mechanical properties. The regression equation between liquid limit and plastic index was:IP=0.43(WL-10.8), which is different form other plasticity charts. Meanwhile, it is different from Casagrande's plasticity chart which can be described as IP=0.73(WL-20). Soil region should be taken into consideration during soil classification.
