中文摘要：

岩体力学参数的测定是岩土工程分析、设计的基础性工作。一般地，为了减小工作量和节约研究经费，须利用有限的室内实验样本的测定值，通过对有限实验样本数据的回归分析整理，确定岩石强度参数，进而估计岩体强度参数。介绍了常用的几种岩体力学参数的确定方法，在岩块的变形和强度参数及岩体结构面的野外统计窗资料的基础上，利用Hook-Brown准则进行坚硬节理岩体力学参数的选取，在对比研究的基础上，说明了Hook～Brown准则公式的合理性。

英文摘要：

A basic work for rock engineering design and analysis is how to measure rock mechanics parameters. Generally, in order to reduce work load and save research costs, it must use the limited measured value of the indoor - experimental samples and regression analysis of data collated to determine rock mechanics parameters. In this paper,some methods to determine mechanical parameters of rock mass are introduced. Based on comparative study, the rationality of these modified expressions is further explained. Based on the data of deformation and strength of rock from test and the statistic structure plane data of rock masses from site, Hook - Brown criterion was applied to estimate the deformation and strength parameters of hard jointed rock masses. Based on comparative study, the rationality of Hook - Brown criterion is further explained.
