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 doubleshield TBM is adopted to realize construction function. The backup 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 backup systems needed for separate launching of doubleshield 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 doubleshield TBM can be disconnected at any position between the main body and the backup system or between the main body and part of backup system.
