江西瑞昌某填方边坡稳定性分析及治理工程措施

Stability analysis and treatment engineering measures of a filling slope in Ruichang,Jiangxi Province

以江西省瑞昌市矿石运输廊道项目仙姑台段填方边坡为研究对象,分析了该边坡的地质环境条件、边坡特征及变形机制,采用极限平衡法对边坡在天然和暴雨工况下的稳定性进行了评价,结果表明两种工况下该边坡均处于不稳定状态,潜在最危险滑动面为素填土与粉质黏土接触部位。针对边坡的不稳定性问题,提出了锚拉抗滑桩、钢筋混凝土板墙、浆切片石护坡墙、截排水沟等综合治理措施。

This article takes the embankment slope section of the Xiangutai segment of the ore transportation corridor project in Ruichang City,Jiangxi Province as the research object.It analyzes the geological environmental conditions,slope characteristics,and deformation mechanisms of the slope.The stability of the slope under natural and heavy rain conditions was evaluated using the limit equilibrium method.The results show that the slope is unstable under both conditions,with the potential most dangerous sliding surface being the contact area between the plain fill and the silty clay.In response to the instability of the slope,comprehensive management measures such as anchor anti-slide piles,reinforced concrete slab walls,grout slice stone revetment walls,and drainage ditches are proposed.
