摘　　要：根据桥址自然条件及景观要求,藏龙二桥主桥采用（40＋5×60＋40）m多孔V形刚构桥,联长380 m,墩身高度5.5~8.5 m。主梁采用单箱单室预应力混凝土箱梁,下部结构采用V形墩。设计中通过联中合理设铰及采用合理的桩基布置形式和桩径,实现多孔长联V形刚构桥的建设。According to the requirements of the site natural conditions and the landscape of thebridge, Canglong Bridge(II) is using(40 + 5 × 60 + 40) m multi-span V-shaped rigid frame bridge with the coupling length of 380 m and the pier height of 5.5 ~ 8.5 m. The main girder is adopting a single box & single room prestressed concrete box girder, and the substructure part is adopting V-shaped pier. The design of setting up reasonable joint hinge and using the reasonable arrangement of pile foundation and pile diameter can realize the construction of multi-span long coupling V-shaped rigid frame bridge.
