| 摘 要： | 为了解决2011年和2012年北京2场强暴雨期间京承三期高速公路道路边坡出现的滑坡问题,对道路边坡26处滑坡处进行实地调查,同时分析暴雨中出现边坡滑坡的原因和发生机制.结果表明：京承高速公路边坡出现滑坡主要存在边坡植被层滑坡、六棱花饰护坡冲毁、坡顶垮塌和坡体滑动等7方面问题.在此基础上,提出了完善坡体内外的截排水系统、避免形成大面积汇流、挂网绿化应对植被层与坡面之间加固等几方面对策和建议,可为今后边坡防护设计和暴雨条件下边坡滑坡应急处理提供依据和参考.

| Abstract: | We investigated 26 road slopes and slide fields in order to solve the highway road slope landslide problem in heavy rainstorms at Beijing-Chengde Expressway during 2011 and 2012. At the same time, we clarified the mechanisms of the landslide. The results showed that there were seven problems which caused road slope landslide, including slope vegetation layer landslide, six-arris floriation revetment washing out, slope collapse, slope slide and so on. Based on the analysis, we propose some countermeasures and suggestions, including improving the slope to drainage system in vivo and in vitro, avoiding large areas of confluence, reinforcing layers and slope by the net green vegetation and so on, for road slope protection. This paper would provide theoretical basis and reference for future road slope protection designs and emergency treatment for the landslide under storms. |
