摘要
奉(节)云(阳)高速公路RK96+380～+630段发育有一处滑坡病害体,公路在此处以分离式路基挖方形式通过,路堑部分开挖后,边坡出现坍塌现象,在强降雨和路基的进一步开挖下,滑坡变形加剧,致使施工暂停。经过滑坡治理方案专项勘察后,设计采用刷方减载、预应力锚索抗滑桩、锚杆框架对滑坡进行治理,现已进入施工阶段。
There have developmented a landslide in Fengjie-Yunyang highway RK96＋380～ ＋630 paragraph where separate the form of digging through the roadbed. After cutting by excavating, we found the phenomenon of slope sloughing. The deformation of landslide is intensification because high rainfall and further excavating of roadbed, so the construction was forced to stop temporarily. After specific investigation of measures of harness about Zhoujiabao landslide,we decided to using these project of landslide contro, such as brushing square and load reduction, anti-slide pile with prestressed cable, anchor bolt frame. It is entering construction stage.
