摘要
通过对西(西昌)攀(攀枝花)高速公路新九地区昔格达地层中粉质细砂岩及粉质页岩物理特性及工程特性的研究,得到昔格达地层的岩性特征,以及昔格达地层抗剪强度指标与含水率的关系,由此得出昔格达地层在干燥情况下自稳性较高的结论,对西攀高速公路建设具有指导意义。
Through the study on physical characteristics and engineering characteristics of farinaceous gritstone and farinaceous shale of Xigeda strata on the Expressway from Xichang to Panzhihua in Xinjiu District, the lithologic features and the relation between shear strength and water content are got.The conclusion is received that the slope has very high steady itself under aridic condition in Xigeda strata.The conclusion has important guiding significance for the construction of Xi-Pan Expressway.
