川藏公路沿河路基水毁成因分析与工程防护
Research on Causes and Prevention Methods of Water Damage to Sichuan - Tibet Highway
【摘要】 川藏公路(西藏境内部分)地处青藏高原的西南部,由于其沿线所处地区的特殊地质、地貌、气候、水文条件影响,因而沿河路基水毁现象十分严重。在实地调查的基础上,对川藏公路的水毁成因、类型进行了分析,井就防治方法提出了建议。最后以川藏公路K4238+196—K4239+150段典型水毁为例,分析了各种防治措施的可行性。
【Abstract】 Sichuan -Tibet Highway is located in the southwest of Qinghai -Tibet Plateau. Water damage to roadbed near rivers along the highway is very serious because of the complicated characteristics of geology , geomorphology, climate and hydrology. Based on field investigations, the causes and types of water damage were discussed, and the prevention of it were put forward. Finally, the application of prevention methods of water damage was applied in the K4238 + 196-K4239 + 150 section of Sichuan -Tibet Highway.
