摘　　要：上海市轨道交通16号线地下段工程采用大直径盾构施工,其内径达10.4 m,隧道内部采用钢筋混凝土中隔墙板进行上、下行分隔,为确保中隔墙的安全,需要定期、快速、全覆盖检测其状态。本文针对16号线大盾构中隔墙结构的特点,创新研究了一种通过相对倾角检测中隔墙墙体状态的技术方法,并采用移动扫描的方式进行中隔墙快速、全覆盖检测;介绍了新型中隔墙监测技术的原理、方法和相关理论模型,结合项目实践通过重复扫描数据和全站仪方式检测验证并估算了该方法的精度。结果表明,该方法对于快速筛查和定位中隔墙有问题区域有良好的效果,具有检测效率高、自动化程度高等特点,对各类交通市政工程中隔墙检测具有参考意义。The metro tunnel of Line 16 of Shanghai is a 10.4 mdiameter singletube shieldbored tunnel with separation wall,the interior of tunnel is separated by reinforced concrete wall panels.To ensure the safety of the separation walls,a regular,rapid,and full coverage monitoring method is required urgently.This article studies a moving-scanning monitoring method that can reflect the state of the separation wall through special relative tilt angle of the wall.It introduces the principles,methods,and theoretical model of the new monitoring technology for separation walls based on practical engineering cases.The accuracy of this method is estimated and verified through repeated scanning and total station testing.The results show that this method has good performance in quickly screening and locating with problem area of the separation wall.Also it has characteristics of high detection efficiency and high degree of automation,which can be referenced for tilt measurement of the separation wall in areas of traffic and municipal engineering.
