摘要
以湘西高速公路红砂岩为研究对象,分析了红砂岩沉积环境和地质构造特征;阐述了红砂岩地层岩石组合类型、岩石学特征和物理力学性质.指出了红砂岩主要工程地质特性为遇水易软化、崩解、发育泥化夹层和层间软弱面.结合工程实例,采用地表位移监测、深部位移监测等多方面的变形监测方法对坡体的变形进行监控,同时结合该路段边(滑)坡的稳定性分析计算,对坡体的稳定性进行了评价.
This paper analyses the depositional environments and geological structual characteristics of the red sandstone in Xiangxi expreeway. It also describes the rock＇ s combination types, petrologic characteristics and physical - mechanical properties of the red sandstone. The red sandstone are easily intenerated and disintegrated when watering, with interlayer iargillization, weak interlayer development. Through the use of surface displacement monitoring, the deep displacement monitoring and many other methods to monitor deformation of the slope with engineering example, the slope stability is evaluated combined with the slide slope stability analysis.
