摘要
结构面是影响公路隧道围岩稳定的重要因素。本文引用最新研究成果,系统地分析了结构面空间方位、几何参数和抗剪强度对公路隧道围岩稳定的影响。根据工程实践,探讨了RQD指标运用的若干问题,推荐了JRC的定量统计估测方法。
Discontinuity is a key factor of stability of highway tunnel wall rock. In the paper, the relationship between orientation, geometry parameter and shear strength of discontinuity and stability of highway tunnel wall rock is analysed systemlaticaly by some new achievement in scientific research. Besides this, several viewpoints about RQD are discussed, and a new method of evaluating JRC is recommended.
