摘　　要：确定大体积节理化岩体强度与力学参数是很困难的,这主要是由于节理化岩体试件尺寸太大及岩体所含节理裂隙所致.然而广义HOEK-BROWN准则的出现,为此提供了解决问题的新途径.本文提出了一种确定大体积节理化岩体强度与力学参数的简易经济的新方法——地质强度指标GSI法.The determination of strength and mechanical parameters of massive jointed rock mass is a difficult problem. Because the sample size of jointed rock mass is very large and the rock mass is composed of rock and joint and fissure. A new avenue for solving this problem had been provided by the generalized Hock-Brown criterion. In this paper, an economical new method is proposed that is Geological Strength Index （GSI） method.
