| 摘 要： | 目前国内山岭隧道多数采用人工开挖，机械化、自动化水平低，不能满足隧道快速施工的要求。结合某隧道施工实践，介绍了人工开挖和双台车开挖机械设备配套、光面爆破技术，统计隧道开挖各工序的消耗时间，预估单台车开挖的时间消耗，并以此为基础详细分析、计算了各自施工成本组成，得出了台车开挖施工成本低，节约循环时间，更有利于快速掘进的结论。

| Abstract: | At present,most of the mountain-crossing tunnels in China are constructed by manual excavation method,which can not satisfy the requirements of rapid tunnel excavation due to its low mechanization and automatization level.Based on the experience in the construction of a tunnel,the authors introduce the equipment matching for manual excavation and excavation by double drilling jumbos respectively and present the smooth blasting technology.The authors summarize the time required by each excavation step of man... |
