公路排水设施中设计降雨重现期的研究

在公路排水系统设计中，降雨重现期是一个非常重要的参数。我国公路排水设计降雨重现期偏大，尤其对坡面排水要求过高。路界表面排水设施的设计降雨重现期需综合考虑排水设施类型，公路所在地区的地形、地貌以及损坏的后果及修复的难易程度等因素，提出一个可供设计人员选择的范围值，达到安全、经济的目的。

Investigation on Design of Rainfall Reappearing Period in Highway Drainage Facilities

In design of highway drainage system,the rainfall reappearing period is a very important parameter.In our country the rainfall reappearing period in highway drainage is designed oversized,especially for slope drainage which is excessively required.During design of the rainfall reappearing period in drainage facilities for surface of embankment the factors such as types of drainage facilities,terrain and geomorphy of regions where the highways are located,consequences of damages and difficulties for repair,e...
