Design of Pavement Drainage for Harbor Road

该文简要介绍了港区道路路面排水的特点,从路表排水、中央分隔带排水、路面结构内部排水三方面详细探讨了公路路面排水设施的布置形式,指出路面排水设计应根据公路等级、降水量、路线纵坡等因素,并结合路基横断面布置、路基挖填情况等,布置排水设施,形成完整、畅通的排水体系,保证路基路面的稳定以及港区行车的安全。

The article briefly introduces the characteristics of the pavement drainage for the harbor roads,discusses in detail the arrangement type of the drainage facilities for highway pavement from three aspects of the drainage of road surface,drainage of central separation strip and inner drainage of pavement structure,points out that the design of pavement drainage should be based the factors of highway class,rainfall,line longitudinal slop and etc.According to the transactional layout of roadbed and the excavation and filling of roadbed,the drainage facilities are arranged to form the integral and smooth drainage system for guaranteeing the stability of the roadbed pavement and the safety of vehicle draining in harbor area.
