| 摘 要： | 金沙江溪洛渡水电站对外交通专用二级公路所经新桥古崩塌体(岩堆)规模巨大，形成历史久远，当地人民称其为“垮山地势”。新桥滑坡群是在新桥古崩塌体基础上形成的。由3块小滑体(E、F、G)构成的一个大型的岩堆滑坡群。每个滑坡规模不等，发育阶段不同，成因各异。新建二级公路推荐方案路线垂直于E、F、G3个滑坡主轴线，从滑坡体中上部通过。文章通过分析滑坡所处的工程地质环境，详细描述了各滑坡的工程地质特征，在定性及定量两个层次上综合评价了该滑坡群的稳定性，分析预测了工程对其可能产生的不利影响。根据该滑坡群的工程地质特征，针对性地提出了对直接威胁路线安全的E、F、G3块滑体的综合治理措施。从工程角度出发，总结了滑坡区的公路选线及治理原则。

| Abstract: | The Xinqiao ancient large-scale landslip was named as "collapse mountain relief" by local residents,where the special second-class highway of the Xiluodu Water Power Station on Jinsha River passes.Xinqiao landslide group is a large-scale rock accumulative landslide,which contains three little landslides(E landslide,F landslide and G landslide),formed on the Xinqiao ancient landslip.The route of new second-class highway in recommending project is perpendicular to the principal axes of these three landslides,and gets through the upper-middle part of the landslides.Based on the engineering geological environment of this landslide group,this paper analyzes the engineering geological characteristics of the landslide group and evaluates the stability of them in quantity and quality.Meanwhile,the paper predicts the probable unfaverable influence to the landslides caused by the new highway project.Finally,the paper puts forward a sets of synthetical treatment measures for these three landslides.From the point of view on the highway project,the principles of route selection and treatment measures are summarized. |
