摘　　要：新建天平铁路六盘山隧道进口为双线隧道,隧道开挖断面大、工期紧,为加快施工进度,选择合理的斜井转正洞施工方法具有重要的意义。介绍了由小断面进入大段面施工的直接一次切入法,结合六盘山隧道进口斜井进入正洞交叉口段施工为工程背景,对小断面斜井进入正洞施工的施工技术进行了详细探讨。New Balance railway tunnel is the two-lane tunnel in Liupan Mountains,which has the features of a large section and the tunnel excavation,tight schedule.In order to speed up the construction schedule,selecting a reasonable method of tunnel construction shaft regularization of has great significance.In this paper,the author introduced plunge methods from light section to big one.Combining background of construction technology of NO.1 inclined shaft and crossings in Liupan Mountains,the author expounded construction technology from light section to big one.
