水对公路的影响很大,山区公路水毁点多、面广、破坏力强。山区高速公路水毁的多发部位往往集中在一些特殊路段。山区的地形地质、水文、气象条件,对山区高速公路排水系统有一定的约束和特定要求。结合广东省阳江至阳春高速公路的建设,研究山区高速公路排水系统,分析其排水系统水毁机理,提出适合于山区高速公路关键部位的排水设计优化方法及改进措施。
Water has a great impact on the road, mountain road destroyed more water points, a wide range of destructive power. Frequently damaged mountain highway highway parts concentrated in some special sections. Mountain topography and geology, hydrology, meteorological conditions on the mountain highway drainage system has certain constraints and specific requirements. Based on the construction of Yangjiang-Yangchun Expressway in Guangdong Province, the drainage system of mountain highway is studied, the drainage mechanism is analyzed, and the drainage design optimization method and improvement measures suitable for the key parts of expressway in mountain area are proposed.
