关于桥面表面排水若干问题的探讨

桥面排水不畅会降低桥梁的通行能力，影响行车安全。在一定的行车速度下，车轮胎面与路面间积水达到某一厚度值，会导致车轮发生“飘滑现象”。为了保障行车安全，桥梁排水系统应有足够的排水能力，确保桥面过水断面在行车道内的水深不至于引起车轮飘滑。就桥面行车道内过水断面水深的控制要求、连续坡桥和平桥的桥面排水系统设计和验算方法等问题进行了深人探讨。

Discussions on Drainage of Bridge Surface

Inadequate sufficient bridge surface drainage decreases the traffic capacity and affects driving safety. When the sheet flow on pavement due to precipitation is in sufficient depth, the tire may separate from the surface. To reduce the risk of motorist hydroplaning, the drainage system with gutters should be designed to avoid the accumulation of water. This paper discusses the calculation of drainage of constant grade and plate bridges.
