摘要
本文主要研究混凝土护坡对边坡稳定性的影响,基于强度折减法,运用ABAQUS数值模拟手段,对未护坡边坡及不同厚度混凝土护坡后的边坡进行稳定性分析。分析其结果表明,混凝土护坡会使边坡破坏时的塑性贯通区下移,且能使边坡安全系数略微增加。护坡厚度对边坡稳定性的影响不大。混凝土护坡并施加坡底堆载能有效增加边坡安全性,提高边坡的安全系数。
This paper mainly studies the influence of concrete slope protection on slope stability. Based on the strength reduction method, ABAQUS numerical simulation method is used to analyze the stability of slopes without slope protection and with concrete slope protectionof different thicknesses. The analysis results show that concrete slope protection will cause the plastic breakthrough zone to move down when the slope is damaged., and the safety factor of the slope will increase slightly. The thickness of the slope protection has little effect on the stability of the slope. Concrete slope protection and application of slope bottom loading can effectively increase the safety of slopes and enhance the safety factor of slopes.
