前言江西贵溪冶炼厂冶金大道跨越浙赣铁路的立交桥主梁长度为44.76m的钢筋混凝土斜腿刚架桥。桥面宽度:净—9+2×1.5m人行道。设计荷载汽—20;验算荷载挂—100。桥上有两根φ500水管与电缆管道。立交桥跨越双线铁路和铁路通讯线路,其中复线尚未修建。为了满足公路桥梁轴线与铁路轴线斜交47°后的双线铁路净空限界和通讯线路的限界,立交桥主孔跨径定为30.0m,边复孔跨径13.38m。
Preface Jiangxi Guixi Smelter Metallurgical Avenue across the Zhejiang-Jiangxi railway overpass girder length of 44.76m of reinforced concrete slanting legs rigid frame bridge. Deck width: net -9 +2 × 1.5m sidewalk. Design load steam -20; check the load hanging -100. There are two φ500 pipes and cables on the bridge. Overpass over the two-lane rail and railway communications lines, including the second line has not yet been built. In order to meet the clearance of the two-lane railway and the limit of the communication line after the axis of the bridge between the axle of the highway and the railway is inclined by 47 °, the span of the main passage of the overpass is 30.0m and the cross-over span of the sidetrack is 13.38m.
