针对南方山区高速公路高路堑边坡滑坡这一工程难题,结合实体工程,提出了南方山区高速公路高路堑边坡滑坡处治的一般思路;对南方某山区高速公路高路堑边坡滑坡成因进行了调查分析,根据边坡工程地质状况和施工条件,提出了"桩板墙+预应力锚索地梁+坡面防护+排水+刷方减载+夯填裂缝"的强支护处治方案;应用FLAC3D对处治后的边坡进行数值模拟分析,分析结果表明处治方案安全可靠;处治后,对边坡进行动态监测,监测数据表明,边坡已处于稳定状态,处治方案可行性强.

　　The high cutting slope landslide of mountain highways is one of main engineering problems.Relying on the practical engineering, a general method to solve the High cutting slope landslide was put forward.The investigation was done to analyze the causes of the landslide.According to the engineering geology and construction condition, a treatment plan of "Sheet-pile Retaining Wall + Prestressed Concrete Beam + Slope Protection + Drainage + Lash-up Reducing Load + Ram and Fill Cracking " was gave.The FLAC3D was used to do numerical simulation a...
