摘要

    摘要
  • 摘要: 以反倾岩质边坡为研究对象，建立了由一组结构面切割时边坡稳定性系数的力学计算方法。根据岩块结构面的受力模式，构建了岩块结构面的断裂力学模型，并基于断裂力学建立了各岩块结构面等效应力强度因子的求解方法和稳定性判据。引入Kelvin蠕变模型，获得了t 时刻岩块结构面等效应力强度因子的求解方法和结构面长度计算方法，为反倾岩质边坡的防治和监测提供了理论依据。以边坡内各岩块的转角为关联变量，量化了岩块转动后岩块间的相互作用力，建立了岩块转角的计算方法。最后，通过实例分析，表明建立的反倾岩质边坡破坏的力学分析方法计算结果与实际情况基本一致。
    Abstract: For the anti-inclined rock slope with a group of fissures, a mechanical method for its stability is proposed. At first, based on the bearing mode on the rock block, a fracture mechanics model is established. Through fracture mechanics, a method of the equivalent stress intensity factors for rock blocks and the relevant stability criteria are presented. By introducing the Kelvin creep mode, the methods for the equivalent stress intensity factors and length for fissure of the rock blocks at any time are obtained. It may provide a theoretical basis for controlling and monitoring the anti-inclined rock slope. Then taking the rotation angles of the rock blocks for relation variables, the interaction force between the rock blocks after rotation is quantified, and the relevant method is put forward. At last, through an example, the results calculated by the proposed method for anti-inclined rock slopes agree with the actual situations.
