摘　　要：为保证在不具备整体始发空间的条件下双护盾TBM分体始发顺利实施,以青岛地铁1号线海泊桥站为例,针对城市地铁隧道施工始发场地有限的客观条件,以实现施工功能为导向,通过配套设备的优化布置并最大限度地利用双护盾TBM自身配置实现有限场地内最经济的TBM分体始发,并对分体始发的基本方案进行探讨。经研究分析可知:1)分体始发时双护盾TBM需具备的基本配套系统为高(低)压供电系统及控制系统、冷却水系统、液压系统、润滑系统、脂密封系统、压缩空气系统、豆砾石回填系统、注浆系统、导向系统及除尘系统; 2)通过管线、线缆的延伸,双护盾TBM可在主机与后配套之间或主机与部分后配套之间任何位置断开。Due to the limited space of TBM launching area of Haiboqiao Station on Qingdao Metro Line No.1,the separate launching technology of double-shield TBM is adopted to realize construction function.The back-up system is improved to realize separate launching of TBM with the lowest cost;and the basic separate launching scheme is discussed.The analytical results show that:(1)The basic back-up systems needed for separate launching of double-shield TBM include high/low voltage power supply and control system,water cooling system,hydraulic system,lubrication system,grease sealing system,air compression system,back filling and grouting system.(2)By lengthening the pipelines and cables,the double-shield TBM can be disconnected at any position between the main body and the back-up system or between the main body and part of back-up system.
