摘要
为解决西安地铁地裂缝带供电设备安装问题,研究了地裂缝活动规律及地裂缝带土建结构处理方案,并在此基础上,对供电设备各种安装方案进行比较分析。其中,对刚性接触网关键部件进行了有限元分析计算,对环网电缆的敷设安装采用特殊调节型支架等方案。研究成果解决了工程实施难题,对后续工程具有借鉴和指导作用。
To solve the problems of power supply equipment installation in the ground fissure zone of Xi′an metro,the laws of ground crack activities and the treatment schemes of civil construction on the zone are studied.On this basis,various schemes for power supply equipment installation are compared and analyzed.The key components of the rigid catenary are specially calculated by using the finite element analysis method,and special adjustable stent is used in the ring network cable installation.The research has solved problems of engineering implementation,providing a reference and guidance for the subsequent engineering practices.
