Quantitative Evaluation and Classification Method of the Cataclastic Texture Rock Mass Based on the Structural Plane Network Simulation
Abstract The structural plane of a rock mass is the indispensable premise for studying and understanding cataclastic texture rock masses, and it is the main reason for the intense heterogeneity of cataclastic structural rock masses. The plane is also the key to classifying the characteristics of cataclastic texture rock masses and quantifying the degree of fragmentation. In this paper, through a thorough investigation of structural plane characteristics, a statistical analysis of the geometric characteristics of structural planes, a network simulation and an analysis of structural planes, a quantitative description index and a quantitative evaluation index are proposed and analyzed from the “point-pine-plane” perspective. A quantitative description index for trace line node density, trace line segment length and crack surface polygon area are proposed based on the structural characteristics of cataclastic texture rock masses. To evaluate fragmentation degree, a trace line node index, a trace line segment length index and a crack surface polygon index are proposed as quantitative evaluation indices. Results show that the relevant indices can effectively identify the structural characteristics and fragmentation degree of cataclastic rock masses. According to the “classification of rock mass from the structural characteristics and fragment degree” approach, a cataclastic texture rock mass classification method is proposed. Taking the example of the cataclastic texture rock mass in the Daguangbao landslide, the quantitative evaluation index and the cataclastic texture rock mass classification method are applied to effectively solve the problem of quantitative evaluation and classify the cataclastic texture rock.
