摘要
论述了裂隙岩体中的结构面的产状、分布、密度和结构面的内摩擦角的统计模型，提出了多组结构面同时存在的分组结构面间距统计法则，阐述了结构面的产状、边线长度等几何参数和内摩擦角的模拟模型，引用块体理论和Ｂａｙｅｓ推测公式建立了巷道围岩中的“危石”预测模型。
The statistical model is discussed for the occurrence, distribution, density and internal friction angle of the structural plane in fractured rocks. The statistical rule is proposed of the distance between the structural planes in classified groups when many groups of structural planes exist at the same time. The simulation model is explained for the occurrence, trace-length and internal fraction angle of the structural plane.The prediction model is established for the dangerous rock in surrounding rocks of roadway with block theory and Bayes prediction farmula.
