摘要
工程岩体的失稳几乎都是沿着结构面发生的。而岩体结构面的抗剪性质并不完全满足莫尔-库仑准则,因此在岩质边坡的稳定性分析中采用莫尔-库仑准则有可能会带来较大误差。本文简要的回顾了岩体结构面抗剪强度估算方法发展的历程,提出了基于JRC-JCS模型计算等效抗剪强度参数的概念和方法,并通过简单计算实例阐明了这一方法在处理实际工程问题中的特点。
Almost all destabilization of engineering rock mass happen along joint,while shear behavior of rock joints can ,t strictly meet Mohr -coulomb failure criterion,therefore using Mohr -Coulomb failure criterion to estimate stability of rock slope will cause error.In this paper course of development of shear strength estimating method of rock joints is reviewed,epuivalent conception and methods of shear strength parameter based on Barton ,s JRC-JCS model calculation is present-ed.Finally,simple case is used to illustrate virtues in dealing with practical engineering problems .
