摘　　要： 桥面排水不畅会明显降低桥梁的通行能力,直接影响行车安全。拼宽桥梁受原桥排水设施的限制和影响,如何优化改进排水设施、保证行车安全,成为施工设计人员必须面对的现实问题,本文从厦蓉高速龙门至漳州段改扩建工程入手,就改扩建桥梁桥面径流宽度问题,分析其对行车安全的影响,针对这一问题提出具体优化措施,以供探讨。 Poor drainage of the bridge deck will reduce the traffic capacity of the bridge, affecting traffic safety. Widening the bridge by the original bridge drainage restrictions and impact, optimizing and improving the drainage facilities, to ensure traffic safety has become a realistic problem which must be faced. This article discusses the Xiarong expressway （ from Longmen to Zhangzhou） reconstruction project of rebuilding the bridge deck width runoff problems, analyzes its impact on traffic safety. To solve this prob-lem ,the author put forward specific optimization measures for discussion.
