| 摘 要： | 新建城市轨道交通穿越既有线为重大风险工程,综合上跨和下穿两种形式的穿越更应严格控制既有线的变形,保证既有线的安全运营.通过第三方监测和微量位移技术相结合的方式,对首都机场线东直门车站上跨和下穿既有13号线折返线工程进行变形控制.监测过程中密切关注隧道结构和轨道结构的变形,发现多次数据超值现象,经过自动化监测系统和顶升系...

| Abstract: | It is an important high risk engineering project that the new urban railway transits existing traffic stations or lines.Strict deformation control should be taken for the project of crossing over and under passing of an existing metro tunnel,so as to keep the existing metro tunnel to operate safely.The coalescence of third-party monitoring measurement and synchronous lifting control technology is used for deformation control of the international airport line Dong zhimen station project which crosses the exi... |
