摘要
以国道G318线某段公路灾后恢复重建工程为依托,进行现场勘察及室内试验,深入研究坍塌岸坡区发育变形历史,分析其成因机制;对滑坡进行天然、暴雨及地震工况下的稳定性分析;总结出临水区公路灾毁工程保通思路与措施:采取对内侧边坡进行开拓、设置抗滑桩+锚索肋板墙等综合支挡措施,坡体在各类工况下均处于稳定状态,经近一年监测未见异常,防治措施合理可行。
Based on the post-disaster recovery and reconstruction project of national highway G318,field investigation and laboratory tests were carried out,the development and deformation history of collapsed bank slope area has been studied in depth,and its cause mechanism has been analyzed.The stability of landslide under natural,rainstorm and earthquake conditions has been analyzed,and the ideas and measures for highway disaster recovery near waterfront has summarized.Comprehensiv retaining measures were adopted,such as,opening up the inner side slope,setting up anti-slide pile and anchor rib wall.the slope body is in a stable state under various working conditions.The monitoring results of nearly a year show no abnormalities,which shows that the prevention and control measures are feasible.
