土体饱和度确定的两个问题

Discussion on degree of saturation determination of soils

本文探讨了有关土体饱和度确定的两个问题。由于试验技术手段的限制 ,土体饱和度只能通过其它物理性质指标之间的关系来求取 ,这样换算得到的饱和度往往偏大。并且 ,根据实验分析 ,地下水位以下的粘性土并不都是饱和的。因此 ,在岩土工程中 。

Two questions on degree of saturation determination of soils are discussed. Owing to testing conditions, the degree of saturation of soils is evaluated by the relationship between degree of saturation and other indexes of physical properties, and this degree of saturation is on the high side. By analyzing on testing results, when we speak of that soils are under groundwater level, it does not mean the soils are saturated. So, soil mechanics for unsaturated soils is studied urgently in geotechnical engineering.
