柬埔寨55号公路边坡稳定分析及加固技术研究

Stability Analysis And Reinforcement Technology Study of A Highway Slope in Cambodia

本文以柬埔寨55号公路边坡为依托工程,使用有限元强度折减法和极限平衡法对边坡进行不同方案下稳定分析。用ABAQUS软件建模分析了不同嵌入深度的锚杆、不同深度的抗滑桩、不同抗滑桩的加固位置对边坡加固的影响。研究结果表明,随着锚杆锚固深度的增加,边坡的安全系数随之增加。抗滑桩在边坡下层能起到更好的加固作用,抗滑桩的锚固深度到达一定值后边坡安全系数趋于稳定。本文的研究结果可为类似工程提供参考。

In this paper, the slope of the Cambodian highway is used as a supporting project, and the finite element strength reduction method and the limit equilibrium method are used to analyze the stability of the slope under different schemes. Using ABAQUS software to model and analyze the influence of different embedded depth anchor rods, different depth anti-slide piles, and different anti-slide pile reinforcement positions on slope reinforcement. The research results show that as the anchoring depth of the anchor rod increases, the safety factor of the slope increases accordingly. The anti-slide pile can play a better role in strengthening the lower layer of the slope. After the anchoring depth of the anti-slide pile reaches a certain value, the slope safety factor tends to stabilize. The results of this paper can provide a reference for similar projects.
