摘要
新龙大桥主桥为(110+200+110)m预应力混凝土箱形梁连续刚构,引桥采用30m、50m预应力混凝土简支T形梁。介绍该桥的总体设计,包括主桥方案选择、主引桥设计等内容。
The main bridge of Xinlong Bridge is a prestressed concrete continuous rigid-frame box girder structure with span arrangement (110+200+110) m, while the approach bridges are designed as the prestressed concrete simply-supported T-girders having spans respectively 30 m and 50 m. In this paper, the overall design of the Bridge is presented, including selection and comparison of alternatives for the main bridge and design process of both the main and approach bridges .
