摘要
提出了一种层状岩体的抗剪强度C，值随方向变化的经验表达式，并与前人的实验结果进行了对比，结果表明二者相当接近。利用这一经验表达式和Mohr－Coulomb准则，采用搜索试算的方法，可判断在三维应力条件下层状岩体是否产生剪切破坏面以及产生时的方位。
The author suggested an empirical expression in which the shear strength parameters C, φ of a layered rock vary with the direction of a plane with respect to the inclination of cleavage. This expression was compared with the experimental results obtained by former researchers, which shows a good agreement between them. By using the expression and Mohr-Coulomb criterion and employing a search-try method, it can be judged whether a shear failure plane within the layered rock under three dimensional stress condition occurs or not as well as what inclination of the failure plane is.
