处于复杂地质构造部位的深挖路堑边坡往往由于自身稳定性储备不足,需要较大的加固治理工作量。本文研究了处在某动力挤压带上,并且具有M形特征的深挖方边坡的地质及水文特征,分析了边坡开挖前后应力状态的变化特点,采用地质分析、刚体极限平衡计算、有限差分数值分析等方法,对深挖路堑边坡稳定性及变形特性进行了分析,并根据分析结果提出了加固措施。本文的研究成果对类似工程可提供参考。
Deep excavation of cutting slopes in complex geological structures often require large amount of reinforcement work due to insufficient reserves of their own stability. In this paper, the geological and hydrological characteristics of a deep excavation slope with a M-shaped feature on a dynamic extrusion belt are studied. The characteristics of stress changes before and after excavation are analyzed. Geological analysis and rigid body limit equilibrium , Finite difference numerical analysis and other methods to analyze the stability and deformation characteristics of deep cutting road slopes, and according to the results of the analysis proposed reinforcement measures. The research results of this paper can provide reference for similar projects.
