摘要
做好黄土路堑高边坡排水系统的设计是保证边坡安全稳定的前提。综合考虑设计降雨重现期、汇流历时、汇水面积等水文参数,根据黄土路堑高边坡的地质、土质及产流特点,应用坡面流理论,推导出流量计算公式。应用该理论公式,讨论了坡度、坡长对设计径流的影响规律。结合水文、水力计算,对黄土路堑高边坡坡体排水设施断面进行优化。该优化法在计算时考虑了当地的地形条件,弥补了公路排水规范法的不足,使结果更准确。本文的研究对完善现有规范,以便适应我国黄土地区飞速发展的公路建设事业具有重要的现实意义。
The drainage design is important for the stability of slope. A formula of runoff quantity is educed by Gradient current theory based on geological and terrene characteristics of loess high slope. The drainage section in the cutting loess high slope was optimization designed by hydrology and waterpower enumerate. This research has important operational significance for the improvement of specification used now, which meet the requirement of the highway construction development in the loess area in China.
