四川西昌昔格达组黏土层物理力学行为研究

The Physical and Mechanical Behavior of Xigeda Clay Layers in Sichuan

在利用西昌地区大量勘察资料的基础上,对黏土层进行了X射线衍射、化学成分分析以及模拟试验等研究.研究结果表明,四川西昌昔格达组黏土层因其特殊的成分特征,表现出不同的物理力学行为特点.对黏土层的物理力学行为进行总结,并提出了非典型性黏土——绿泥石在西昌昔格达组黏土层的黏性中起关键作用的观点.

On the basis of a large number of prospecting datas of Xichang,clay layers were studied and simulation tested by X-ray diffraction,chemical composition analysis. The results show that Xigeda clay layers in sichuan exhibit different physical and mechanical behavior characteristics because of their special compositional characteristics. In this paper,the physical and mechanical behavior of clay layers were summarized and it is proposed that the atypical clay-chlorite in Xigeda sticky clay layer of Xichang plays a key role in perspective.
