摘　　要：为查明西昌钒钛钢铁新基地工程区昔格达组粉质黏土塑性指数的主要控制因素,通过对工程区昔格达组粉质黏土样品矿物组成分析,黏粒含量与塑性指数的关系以及塑性指数与颗粒组成之间的关系分析,最终得到昔格达组粉质黏土样品塑性指数的主要控制因素是其颗粒组成。对该地层上的工程施工以及施工过程中的土质改良具有一定的工程意义。In order to find out the main controlling factors of Xigeda formation silty clay plasticity index in Alunite and Titanium steel new base in Xichang,mineral composition of silty clay samples,relationship between clay content and plasticity index and relationship between plasticity index and particle composition had been analyzed.The conclusion is that the main controlling factor of Xigeda silty clay samples plasticity index is its particle composition.There is some significance for construction and soil improvement during the construction on the formation.
