双护盾全断面掘进机在大坂隧洞软硬岩工程中的应用研究

Application Research of Shield Tunnel Boring Machine on Soft and Hard Rock Engineering in Osaka Tunnel

大坂隧洞工程为国家大型调水工程,灌溉面积上百万亩,但建设和设计之困难程度国内外罕见,也无先例。采用国内外先进的双护盾TBM掘进技术,使掘进顺利进行,该工程已完成主体工程量的95%以上。为国内外长距离、高埋深软硬岩调水工程的输水方法优化及设计与施工提供借鉴及管理成功的实例。

Osaka tunnel engineering, the national large infrastructure construction of water transfer project, has the coverage of effectively irrigated farmland totaling more than one million acreages. It is unprecedented in the world due to the difficulties of design and construction. Owing to adopt the advanced shield tunnel boring machine technology, more than 95 percent of major project has been completed. It is providing reference for optional design and construction management for long-distance, highdepth soft and hard rock water transfer project.
