摘要
为解决轨道交通工程隧内道侵限区段净空不足的工程难题,提出了隧道内侵限区段刚性接触网系统特殊设计原则,并提出了优化接触网平面布置,调整悬挂点间距,选择U型支架安装方式,校核建筑限界,以及凿除部分混凝土和加装绝缘板等解决方案。以国内某工程为案例进行了应用。
In order to solve the problems of tunnel head- room deficiency in rail transit engineering, a special design principle for tunnel headroom sections and the solution to the design of rigid catenary system are put forward, including the optimum catenary plain layout, the adjustment of suspension point spacing, the verification of tunnel con- struction clearance, and so on. This solution has been ap- plied in a certain tunnel project in China.
