多空隙沥青混凝土面层排水设计中的降雨输入

Rain Input in Drainage Design for Surface Layer of Porous Asphalt Concrete Pavement

讨论了道路采用多空隙沥青混凝土面层后 ,排水设计中降雨输入参数的意义及其选择依据 ,包括降雨历时、降雨强度与设计重现期 ,以期对这种路面的排水设计采取相对应的概念与方法。

The importance and the selection basis of inputted rain parameters including rainoff duration, rainoff intensity and design return period in drainage design for porous asphalt concrete pavement are discussed in this paper, which is expected to adopt the suitable concept and method in this kind of issue.
