摘　　要：涉敏感海域的桥梁排水,若直接排放将污染海洋环境,因此需收集桥面排水进行。文章通过工程设计实例,分析涉敏感海域特大桥桥面排水收集的必要性,对桥面排水大方案进行比选,对桥面初期雨水系统和中后段雨水系统进行具体设计计算。基于海绵城市建设理念,在桥面设置环保型雨水口,并结合路基下沉式绿地对初期雨水进行预处理,采用智慧排水系统进行桥面排水系统转换控制,为后续涉敏感海域桥梁设计提供合理化和可行性建议。Bridge drainage involving sensitive sea areas will pollute the marine environment if it is discharged directly,so it is necessary to collect bridge deck drainage.Through the engineering design example,this paper analyzes the necessity of bridge deck drainage collection of extra-large bridge involving sensitive sea areas,compares and selects the large scheme of bridge deck drainage,and carries out the specific design calculation of the initial rainwater system and the middle and rear rainwater system of the bridge deck.Based on the concept of sponge city construction,environmentally friendly rainwater outlets are set up on the bridge deck,the initial rainwater is pretreated in combination with the subgrade sunken green space,and the intelligent drainage system is used to control the conversion of the bridge deck drainage system,which provides reasonable and feasible suggestions for the subsequent design of bridges involving sensitive sea areas.
