本文介绍了一个用于计算严重节理化或风化岩体的经验准则。这一准则引入了完整岩石材料强度这一概念,并采用了两个表示节理化岩体内颗粒互嵌特性的无量纲参数m和s。讨论了岩体分类法在计算这两个参数值时的应用。本文还利用计算实例举例说明了非线性破坏准则在分析边坡过程中的应用。 This article presents an empirical guideline for calculating severely weathered or weathering rock masses. This guideline introduces the concept of complete rock material strength and uses two dimensionless parameters m and s that represent the inter-embedding properties of particles in the jointed rock mass. The application of rock mass classification method to calculate these two parameters is discussed. In this paper, an example is given to illustrate the application of nonlinear failure criterion in slope analysis.
