大别山隧道斜井快速掘进技术分析

Analysis on Rapid Excavation Technology Applied in Inclined Shaft of Dabieshan Tunnel

对合武铁路客运专线大别山隧道斜井初期掘进状况不理想的原因进行了详细分析,针对存在的主要问题,提出了相应的改进措施,从而使开挖方案更科学合理,实现了提高循环进尺、缩短循环时间、严格控制超欠挖,达到了节省工期、降低工程成本的目的。

The article gives a detailed analysis on the initial poor excavation construction of the inclined shaft of Dabieshan tunnel on Hefei - Wuhan passenger-dedicated railway. On basis of the existing problems, the article recommends some countermeasures, which result in higher advance rate, reduced cycle time, minimum overbreak/shortbreak, decreased construction period and reduced cost.
