双模式全断面掘进机探讨

Discussion on Dual-mode Full-face Tunnel Boring Machines

为适应地质的复杂性以及中国国情,探讨双模式全断面掘进机的未来发展趋势,并举例说明双模式全断面掘进机的设计理念,详述其主要结构及适用范围。与单模式掘进机相比,双模式全断面掘进机地质适应性广、设备利用率高、施工成本低,是隧道掘进设备技术发展的主要方向之一,具有良好的发展前景。

The development trend of dual-mode full-face tunnel boring machines is discussed, the design concept of du- al-mode full-face tunnel boring machines is presented and the main structure and applicability scope of dual-mode full- face tunnel boring machines are described in detail. The study shows that, compared to single-mode tunnel boring ma- chines, the applicability scope of dual-mode full-face tunnel boring machines is more extensive, the availability of dual- mode full-face tunnel boring machines is higher and the tunneling cost of dual-mode full-face tunnel boring machines is lower. Conclusion is drawn that the dual-mode full-face tunnel boring machine, which is the main development trend of tunnel boring machines, has a splendid future.
