摘　　要：安庆市勇进路大桥为跨越石门湖宽广水域的全长约2.5 km的长大桥梁。在大桥总体设计时,对大桥总体线形、主桥桥型方案、湖区环保防污、湖上施工方案等要点进行了重点研究,再通过权衡取舍,确定了最优的总体方案。这为今后跨越宽广生态湖区的类似桥梁建设提供借鉴与参考。The Yongjin Road Bridge in Anqing is a long&large bridge with a total length of about 2.5 km that spans the broad waters of Shimen Lake.During the overall design of the bridge,key points such as the overall alignment of the bridge,the main bridge type scheme,the environmental protection&pollution prevention in the lake area,and the construction scheme on the lake are emphatically studied,and then the optimal overall scheme is determined through trade-offs.It will provide reference for similar bridge construction across the broad ecological lake area in the future.
