摘要
鉴于青藏线西格二线关角隧道的特殊性,通过对国内已开通可借鉴的长大隧道京广线大瑶山隧道、兰武二线乌鞘岭隧道及青藏铁路既有关角隧道情况进行调研、测试、分析,综合新关角隧道环境条件、方案可靠性、维修维护、投资等各方面因素,推荐区间采用ZPW-2000系列无绝缘轨道电路,隧道内进行轨道电路分割方案。
In view of the special nature of Guanjiao tunnel on Qinghai-Tibet Xining-Ge＇ermu second-line and on the basis of the investigation, test and analysis of the existing long tunnels on some domestic railway lines, this paper recommends ZPW-2000 non-insulation track circuit in the section between stations and track circuit segmentation in the tunnel with respect to environmental conditions of the tunnel, reliability of plan, maintenance and investment..
