试论目前高速公路排水设计的不合理性

On Nonrationality of Freeway Drainage Design at Present

高速公路的排水设计对路基的稳定性和路面的使用寿命具有显著影响。通过对目前高速公路边沟、中央分隔带、桥梁泄水孔的排水能力的计算与分析 ,并结合高速公路建设过程中的工程实例 ,初步论证目前高速公路排水设计的不合理性 。

The drainage design of freeway has notable enfluence on the subgrade stability and pavement service life.By means of calculation and analysis of the side ditch,the median divider and the drainage ability of weep-hole of bridge,at present on freeway,and in the light of some engineering examples in the process of freeway building,the nonrationality of freeway damage design of present is preliminarily demostrated,moreover some valuable suggestions are put forward.
