盾构法与矿山法相结合施工技术

TBM Tunneling and Drill-and Blast Method Combined Construction Techniques

深圳地铁一期工程益田～香蜜湖区间隧道,采用盾构法与矿山法相结合的施工技术,既缩短了工期、降低了工程成本,又维持正常交通,保护了沿线建筑物,达到了保护环境的目的,介绍施工步骤和要点,可供类似工程参考。

The Yitian～Xiangmi Lake tunnel section in the 1 st phase of Shenzhen Metro is constructed by drill and blast method and TBM tunneling. Thus, the combination of these two construction method speeds up the construction period, reduces of the project cost, and maintains normal ground traffic operation, as well as protects the building along the tunnel route. This paper, which introduces the construction steps and key points, can be used as a reference to similar projects.
