| 摘 要： | 北盘江大桥主桥为(192+636+192)m单跨双铰简支钢桁梁悬索桥,钢桁梁及桥面板采用缆索吊装系统施工.由于桥址地形陡峭、风环境复杂,一般缆索吊机不能满足施工需要,对缆吊系统的承重索计算、走线设计及跑车系统进行了优化.由于钢桁梁横向宽28m,远大于路基宽度,且缆吊系统承重索的净间距仅19.0m,故钢桁梁节段采取顺路线...

| Abstract: | The main bridge of Beipan River Bridge is a single span two-hinged simply-supported steel truss girder suspension bridge with span arrangement(192+636+192) m and the steel truss girder and deck plates of the bridge were installed by the cable hoisting system.Because the topography at the bridge site is steep and the wind environment there is complicated,the common cable hoisting system could not meet the need of the construction and the calculation and design of the carrying ropes,traveling ropes and trolle... |
