位于地裂缝带的接触轨及架空接触网安装方案分析

Analysis of Contact Rail and Overhead Catenary System in Ground Fissure Areas

地铁工程设计经常存在一些特殊区段,如地裂缝区段,其不均匀沉降将会威胁到接触网系统的装配及相关参数,甚至会造成破坏,进而严重影响地铁的运营安全。结合西安地铁3号线不同地裂缝带的土建结构处理特点,针对接触轨及架空接触网的不同安装特点进行相应的技术方案分析,得出适应不同结构处理方案的接触轨及架空接触网安装方案,满足因地裂缝带结构沉降引起的接触轨及架空接触网调整需求。

Metro project design often comes up against many special sections, such as ground fissures which can damage the installation of OCS and the related parameters, even threaten the operation of metro. According to the suc- cessful civil engineering of Xi＇an metro Line 3 on different fissure sections, and based on the analysis of different OCS installation technologies, several methods of OCS installa- tion in the ground fissure areas are proposed, which can meet the needs of adjustment between OCS and contact track in ground fissure areas to and make the OCS more re- liable.
