Design Characteristics of Fuzhou City Huaian Ming River Bridge

介绍了在闽江分流点下游附近建设桥梁的孔跨布置的控制因素,结合桥位的建桥条件,因地制宜地采用钢箱混合梁斜拉桥,采用阻尼器减小地震响应,在大跨度斜拉桥钢梁上采用复合桥面技术以期提高桥面铺装的耐久性。

The article introduces the control factor of span layout for the bridge constructed near the lower reaches of the branch of Ming River.According to the bridge construction conditions,the steel box combined beam cable-stayed bridge is used to suit the local circumstances,and the damper is adopted to decrease the earthquake response.The compound deck technology is used on the steel beam of the long-span cable-stayed bridge so as to enhance the durability of deck pavement.
