重庆轻轨电缆桥架设计施工方案的研究

Study of Design and Construction Plan for Cable Trough of Chongqing Light Rail

重庆轻轨供电环网电缆在高架区间敷设在线路PC梁下,而在PC梁下环网电缆敷设是供电线路工程的一个难点,本文介绍了重庆轻轨高架区间环网电缆桥架的结构形式、承载要求及设计施工方案,并对其梯形桥架的挠度进行了计算及验证。

Since power supply loop network cable of Chongqing Light Rail will be laying under the PC beam of the line in elevated area, and laying power supply loop network cable is a difficult point in power supply line construction, so the paper introduces the mode of structure, requirements of load and plan for design & construction of cable trough for power supply loop network cable in elevated area of Chongqing Light Rail as well as the calculation and verification of the deflection of trapezoidal cable trough.
