摘要
以四川省攀枝花市某边坡及挡墙工程病害为研究对象,利用传递系数法对其边坡稳定性进行分析计算,对其边坡失稳机制进行了研究。结果表明:天然状态下,边坡在原有挡墙的作用下处于基本稳定状态,而强降雨状态下,原挡墙不满足安全要求。选择原有挡墙+预应力锚索抗滑桩+前后填土注浆+重建截排水系统的组合方案进行加固,治理效果良好。
Taking a slope and retaining wall works hazards in Panzhihua City of Sichuan province as the research object, the slope stability has been analyzed and calculated through transfer coefficient method. The slope instability mechanism has been studied. The result shows that: in the natural state, the slope is basically stable under the action of the original retaining wall. In the heavy rainfall state, the original retaining wall does not meet the safety requirements. The combined scheme of original retaining wall + prestressed anchor cable anti-slide pile+ front and back filling grouting + reconstruction intercept and drainage system has been selected to reinforce the slope which brings a good treatment result.
