宁杭高速公路东芦山超高边坡岩体特征分析

Analysis on rock mass characteristics of Donglushan mount high slope section in Ning-Hang expressway

对东芦山的岩石成因、结构构造,以及物理力学性质等特征进行研究,指出该类岩石在变形特征上可视为均质弹 性各向同性体。依据边坡区岩体构造的基本特征、空间产状、原生结构面性质及分布规律,对东芦山边坡岩体工程地质岩 组和岩体结构类型进行划分。并在此基础上建立东芦山边坡岩体的地质模型。

The rock mass characteristics in Donglushan Mount section, including cause of formation, structure, physical and mechanical characteristics are stidoed. Then it shows that the kind of rock mass can be regarded as homogeneous, elastic and anisotropic from its distortion shape. According to the main characteristics of its structure, spatial attitute, original structural plane, the engineering geological petrofabric and structure types to the rock mass of Donglushan Mount high Slope section are classicified and discussed. On the basis of the above work, the geolgical model of the rock mass has been builded.
