Hoek-Brown破坏准则最初是为了估计坚硬岩石的强度而制定的。由于缺乏合适的替代方案，该标准已被应用于各种岩体，包括质量非常差的岩石，几乎可以归类为工程土。这些应用程序需要对原始标准进行更改。主要问题之一是确定等效粘结强度和摩擦角，以满足根据莫尔-库仑破坏准则编写的软件的要求。本文总结了Hoek-Brown破坏准则的解释，该准则被认为是处理实际工程问题的最好方法。(C)1998年爱思唯尔科学有限公司。
The Hoek-Brown failure criterion was originally developed for estimating the strengths of hard rock masses. Because of the lack of suitable alternatives, the criterion has been applied to a variety of rock masses including very poor quality rocks, which could almost be classed as engineering soils. These applications have necessitated changes to the original criterion. One of the principal problems has been the determination of equivalent cohesive strengths and friction angles to meet the demands of software written in terms of the Mohr-Coulomb failure criterion. This paper summarises the interpretation of the Hoek-Brown failure criterion which has been found to work best in dealing with practical engineering problems. (C) 1998 Elsevier Science Ltd.
