摘　　要：传统的桥梁桥面排水采取直排入河或入江的排水系统已不能满足现今愈来愈高的环保质量要求。针对跨越敏感水体的桥梁排水,为避免初期雨水及发生交通事故导致液体危险品泄漏直接排入水体造成水环境污染,结合工程实际,对跨水体桥梁桥面排水进行有组织排放设计,探讨了桥面收水设施的设置、事故池容积的计算及事故池工艺的设计,研究结果可为新建跨敏感水体的桥梁排水设计提供参考。The traditional drainage system of bridge deck drainage directly into the river can no longer meet the increasingly high environmental protection requirements.For the bridge drainage across sensitive water bodies,in order to avoid the water environment pollution caused by the initial rainwater or the leakage of dangerous liquid by traffic accident directly discharged into the water body,combined with the engineering practice,the design of organized discharge of bridge deck drainage across water bodies is carried out.The setting of the water collection facilities on the bridge deck is discussed,the volume of the accident tank is calculated and the technology of the accident tank is designed.The study results can be referred for the design of bridge drainage across the sensitive water bodies in the future.
