| 摘 要： | 活动断层是伴随地震发生的一种地质灾害,穿越地铁线路的活动断层是地铁建设中的首要技术难题。活动断层的活动对地铁架空刚性接触网悬挂结构产生严重威胁,进而影响到地铁的安全运营。为此,在研究活动断层活动特征及隧道结构处理措施的基础上,提出适应活动断层的架空刚性接触网安装要求的垂直悬挂结构及安装调整方案,并进行有限元分析和试验验证。该研究成果已在乌鲁木齐地铁一号线的建设中得到应用。

| Abstract: | Active fault is a kind of geological disaster accom-panied by earthquake,it is the first technical problem in U-rumqi metro construction. Active fault directly threats the sus-pension structure of overhead rigid contact system,and further seriously affects metro operation safety. Based on a thorough study on the characteristics of the active fault and the counter-measures of tunnel structure,a suspension structure accommo-dated to the installation requirements of overhead rigid contact system and the suspension structure adjustment scheme in the active fault section is presented,which has been verified by fi-nite element analysis and test. The research achievement has been applied in the construction of Urumqi metro Line 1. |
