摘要: 结合西昌钒钛钢铁新基地所揭露的昔格达组粉质黏土的矿物组成及颗粒级配,通过验证性试验及前人研究成果,对黏土矿物及土体的颗粒级配对昔格达组粉质黏土塑性指数的影响进行分析。结果表明:黏土矿物及高粉粒含量是影响昔格达组粉质黏土可塑性的主要因素,高粉粒含量对昔格达组粉质黏土可塑性的影响比粉质黏土中黏土矿物种类及含量对其可塑性的影响大。但粉粒含量对黏性土体的塑性指数的贡献值具有一定范围,一般介于6~10。Abstract: According to clay mineral composition and particle size distribution of Xigeda formation silty claystoneexposed in Vanadium and Titanium-Iron and Steel Base in Xichang, influence of soil particle size distribution andclay minerals on the plasticity index of Xigeda Sity Clay was discussed.Qualitative analysis by verification experimentand other' s researches also were done.The results showed that the clay minerals and high silt content in Xigeda SiltyClay influenced greatly on its plasticity index.The influence of silt content on plasticity of Xigeda was greater thanthat of clay minerals and clay content on plasticity index.The contribution to plasticity index value of silt content hada certain range, usually between 6 ~ 10.
