摘要
高速公路沿线高路堤边坡运营多年后,由于受到边坡所在区域不良工程地质、水文、外部环境、人工堆载、人为开挖破坏及大气降雨等内外因作用下,往往出现不利于边坡稳定性的病害、变形及应力,对高速公路的运营安全非常不利,因此很有必要对公路沿线存在安全隐患的高路堤边坡进行定期监测与定期病害检查,并根据定期监测与检查结果及时进行养护处治与效果验证。结合广东省江肇高速公路K267高路堤边坡养护设计方案综合比较及处治后设计方案的可行性进行了监测验证,可供类似工程提供参考。
As for the high expressway embankment slopes,after years of operation,due to the adverse engineering geology,hydrology,external environment,artificial loading,artificial excavation and atmospheric rainfall and etc,some diseases,deformation and stress against the slope stability would occur.And the safety of the operation of the highway is very unfavorable,it is necessary that regular monitoring and regular disease inspection should be taken for the high expressway embankment slopes with safety hazards,and a timely maintenance and validation should be taken according to the regular inspection results.In this paper,taking account of maintenance design of K267 high embankment slope of Jiang-zhao Expressway in operation and the post-treatment design,a monitoring verification has been carried out,which could provide a theoretical reference for similar projects in the future.
