细粒土的塑性指数与黏粒含量的关系分析

Relationship Analysis Between Plasticity Index and Clay Content of Fine Grained Soil

以天津地区细粒土为例,分析细粒土塑性指数与黏粒含量的关系,细粒土的塑性指数(IP)用光电式液塑限联合测定仪测得,用甲种比重计测得细粒土的砂粒、粉粒及黏粒含量,并对试验结果进行分析,为保证分类定名的准确性,提出不同的土样应选用其中一种试验方法所得结果即塑性指数(IP)或黏粒含量结果来定名分类。

Fine grained soil in Tianjin area as an example,the analysis of fine grained soil plasticity index and clay content,the relation between the fine grained soil plasticity index(IP)with a combined photoelectric liquid plastic limit apparatus,with x gravimeter measured of fine grained soil,sand,silt and clay content and the test results is analyzed,in order to ensure the precision of classification name,put forward different soil samples should choose one of the test method of the results that the plastic index(IP)or clay content classification results to name.
