摘　　要：软弱层带是控制岩体稳定性的重要边界条件。软弱层带的工程特性是其物质基础与环境条件共同作用的结果。研究表明软弱层带的抗剪强度与塑性、干密度和含水量具有明显的相关性,并提出了抗剪强度与三因子之间的经验公式。The weak layers are the most important boundaries controlling rock mass stability. The engineering properties of the weak layer are controlled by the basic substance and environment conditions. The study shows that a good correlativity exists among shear strength,plastic limit,dry density and moisture content,and the experience formula about it is given.

关 键 词：软弱层带 抗剪强度 塑限 干密度 含水量
