摘要
内蒙古鄂尔多斯市西山西路桥采用58 m+140 m+48 m的自锚式悬索桥。桥宽40.1 m,加劲梁采用钢-混凝土组合梁,边跨支点处采用混凝土梁段,主缆锚于其中,结构体系为塔梁分离,加劲梁在边墩及主塔墩上均设竖向支撑,同时主墩处设置抗震限位装置。桥型方案兼顾美学、力学和经济性能要求,建成后将成为新的城市标志性建筑。
With the background of West Xishan Rd. Bridge project in Ordos, Inner Mongolia, the bridge is designed as a self-anchored suspension bridge with the spans of 58 m + 140 m + 48 m and the deck width of 40.1 m. The stiffening girder adopts steel-concrete composite beam, and the supporting point of side span adopts concrete-girder section, which supplies the anchor space of main cable. The structure system is that tower and girder are separated; the stiffening girder is supported vertically both at the side pier & the main tower pier; the seismic limit device is located at the main pier. The bridge plan takes the aesthetics, mechanics & economy performances into account, which will be new city landmark after its completion.
