Abstract:

The Huoshaogou Bishan Bridge in Xining City is an important node project connecting Hailu Road and the east branch of Hailu Road. It is located on the east side of Bishan Park. Its span arrangement is (40+60+40) meters. The superstructure is an open-web arch continuous steel box girder structure, which is composed of multiple arch components to form a multi-level structure. The shape is beautiful and the curve is round and dynamic with good adaptability to the surrounding landscape and site. The factory intelligent processing and assembly based rapid construction methods are used in the construction in order to improve the construction progress and effectively reduce the damage to the weak ecological environments during the construction process. The design scheme has the significant application space in modern urban landscape bridges.
