| 摘 要： | 城市轨道交通列车制式、运行方式、站点设计等与传统的运输方式不同,其活载图式的选择对线路总投资会有直接的影响。根据现阶段国内外有关经验及机车车辆实际情况,对计算跨度10～80m简支梁不同活载图式作用下的换算均布活载效应进行了综合比较。通过理论分析及计算,建议采用0.6UIC作为城市轨道交通工程桥梁活载图式。

| Abstract: | The vehicle mode, operation mode, station design of urban rail vehicle is all different from traditional transit mode. The selection of its live load has direct influence on the total investment of the line. Based on the present domestic and foreign experience of locomotives under the actual situation, the paper did comprehensive compare of uniform live load effect of different live load representative figure for the bridge whose calculation span is of 10~80 m. Through theoretical analysis and calculation, ... |
