岩体基本质量指标BQ与岩石坚固性系数f之间的关系研究
Study on the Relationship between BQ of Rock Mass and f of Rock
摘要
Abstract
In order to establish the relationship between the rock consolidating coefficient f and the basic quality(BQ)index and each mechanical parameter indicator of the rock mass,the following methods were employed for research.Firstly,based on the correlations between the uniaxial compressive strength RC of rocks and both BQ and f,RC was as an intermediate variable to establish a relationship equation between BQ and f.Secondly,based on the correla-tions between the volume joint coefficient JV and both the rock mass quality index DRQD and integrity coefficient KV,JV was as an intermediate variable to establish a relationship equation between DRQD and KV.By further derivation,a relationship equation among BQ,f,and DRQD can be obtained.Thirdly,based on the above relationship equation,the relationship equations of each mechanical parameters of rock mass and f were established.Finally,the research results were applied to the grading the rock mass and estimating various mechanical parameters for the mountainous tunnel engineering of South North Highway in Kyrgyzstan to determine the construction plan.The settlement defor-mation monitoring results indicate that the construction effect of the project is good.关键词
