摘要
在城市轨道交通中采用敞开式TBM,不可避免的要遇到下穿建(构)筑物等问题.以重庆轨道交通六号线敞开式TBM下穿盘溪河过水涵洞为工程依托,根据TBM施工原理,结合线路埋深、地质条件及涵洞特点,提出了敞开式TBM下穿过水涵洞的掘进技术和支护方案,保证了TBM能够快速、安全、优质的下穿施工,并对周边环境的影响降至最低,研究成果可为相关类似工程提供借鉴和参考.
When open TBM using in the urban track traffic project,it would be able to encounter undercrossing buildings inevitably.Based on the open TBM under crossing Panxi river moving water culvert construction in the sixth line of Chongqing track traffic,according to the construction theory of open TBM,and combining with the depth of line,geology conditions and characteristics of culvert,the driving technology and supporting project of open TBM undercrossing construction are put forward to ensure TBM under cross construction rapidly,safely and in high quality,and reduce the influence on the surroundings to the least.The research result can give experience and reference to analogous projects related.
