地质强度指标量化方法综述

A quantification method of geological strength index

在广义Hoek-Brown强度准则中,如何量化地质强度指标GSI取值进而获得贴近工程岩体力学参数的问题,是众多专家学者一直在研究的课题。本文详细介绍了国内外专家对于此问题的最新研究成果,并提出了两个问题:各GSI取值方法的准确程度无法评价的问题;在改进的获取GSI表中,如何选取两个最具代表性的因素来表征岩体结构特征和岩体结构面特征的问题,这两个问题的研究将会推动岩体工程的进步。

In a broad sense of the Hockgeological strength index （GSI） has b they are ever trying to get close to the duced the latest achievements made by Brown strength criterion, the question of how to quantify the value of een extensively researched by numerous experts and scholars while mechanical parameters of engineering rock mass. This paper introexperts from China and abroad, and then it tried to solve two quescannot be determined, and the other is how to choose rock mass structure and those of rock mass structural plane. The solutions to these two questions will be conducive to the development of rock mass engineering.
