| 摘 要： | 针对顺层岩质边坡稳定性监测较难进行的问题，采用应力监测的方法对其进行评价。利用数值计算得出不同结构面间距时的边坡失稳破坏位置为距离坡脚处最近的结构面位置处，并结合理论分析与锚杆监测的现场试验对其进行验证。现场试验结果表明，边坡内部应力在开挖后40天趋于稳定，锚杆受力最大值为30．6MPa，满足钢筋设计抗拉强度要求，表明... |

| Abstract: | Aimed at the problem of difficulty to monitor the stability of bedded rock slope, the method of stress monitoring is used for evaluating it. The numerical calculation method is used to obtain that the failure location with different crack distance is at the ground crack location of nearest slope toe, which is verified through combining with the theory analysis and the field test of bolt monitoring. The research results show that the slope stress tends to stability about 40 days after cutting, the maximum stressing value of the bolt is 30.6 MPa, which could meet the requirements of the tensile strength in reinforcement designing, and indicate that this slope has tended to steady state. |
