本分类采用多因素的综合分类法,以岩体的结构特性为基础来表征其工程地质特征。同时还反映岩体的物理力学特性以及受力时变形破坏的基本方式和规律。分类对岩体特性的分析力求详细、准确,并以岩体的完整性、剪切折减系数和强度指标,用列表法予以相对应,以便尽可能地反映客观实际情况。围岩压力值的确定方法拟用经验、实测和理论计算相结合的方法,避免了各种方法的局限性。
This classification adopts the multi-factor comprehensive classification method to characterize the engineering geological characteristics based on the structural characteristics of rock mass. At the same time, it also reflects the physical and mechanical properties of rock mass and the basic methods and laws of deformation and failure under stress. Classification of rock mass characteristics of the analysis of detailed and accurate, and the integrity of rock mass, shear reduction coefficient and strength indicators, to be mapped with the list in order to reflect the objective reality as much as possible. Surrounding rock pressure to determine the value of methods to be empirical, measured and theoretical calculations combine to avoid the limitations of various methods.
