Abstract
Jinhua to Taizhou railway is designed as a single-track line with reservation for future double-track. There are many difficulties encountered during the design such as scheme comparison between single-track and double-track, project investment, construction safety, progress control and disaster rescue system related to complex terrain and geological conditions. With extensive studies on connection conditions at the ends of the tunnel, setting of meeting station, geological conditions, single-track and double-track, construction methods, disaster rescue, construction period, project investment and environmental protection, a 18. 37 km extra-long tunnel is recommended under the precondition of reasonable progress schedule, less investment and operation expenses and controlled construction safety, and a two-phase implementation, and drilling and blasting method+TBM are also recommended.关键词
