对岩质路堑边坡的稳定性分析时,其坡体的稳定性(或变形)往往受结构面强度、结构面产状与边坡形态的相对关系等因素决定。因此在考虑结构面强度和结构面产状的基础上,必须同时研究边坡形态与结构面产状的组合关系对坡体稳定性的作用和影响。基于此思想,采用有限元分析方法,利用遍布节理本构模型分析结构面倾角的差异对坡体稳定性的影响,并提出对含结构面岩体强度的修正方法。
When analyzing the stability of the rock slope, the stability (or deformation) of the slope is often determined by the relative relationship between the strength of the structural plane, the yield of the structural face and the shape of the slope. Therefore, on the basis of considering the strength of the structural plane and the shape of the structural plane, it is necessary to study simultaneously the effect and influence of the combination of the shape of the slope and the yield of the structural plane on the stability of the slope. Based on this idea, the finite element analysis method is used to analyze the influence of the difference of structural plane inclination on the stability of the slope by using the universal joint constitutive model, and the correction method for the strength of the rock mass containing the structural plane is proposed.
