为论证隧道施工图现场核对与设计优化工作的重要性，依托蒙华铁路隧道工程建设，从隧道进出口位置、弃碴场位置、隧道进洞方式、辅助坑道设置等方面开展隧道施工图现场核对优化工作,并以张裕1#隧道、赵吾4#隧道、中条山隧道、禹门口隧道、大中山隧道、黄柏岭隧道等隧道为例，论述通过采用隧道改路基、暗挖改明挖、调整辅助坑道、增设横洞、大管棚改为小导管、弃碴场位置调整等措施来确保隧道工程建设“安全、合理、经济”。该工作取得了较好的应用效果，可为后续隧道工程建设提供参考。

The field review and design optimization of construction drawing of tunnel is very important. The field review and design optimization of construction drawing of Menghua Railway Tunnel are carried out in terms of locations of tunnel entrance and exit, locations of spoilt disposal areas, tunnel entrance construction method and auxiliary tunnel setting. And then the safe, rational and economical tunnel construction, by adopting tunnel replaced by subgrade, mining method replaced by open cut method, auxiliary tunnel adjustment, adit adding, large pipe roof replaced by small duct and spoilt disposal area adjustment to ensure safety, is discussed by taking 6 tunnels, i.e. Zhangyu #1 Tunnel, Zhaowu #4 Tunnel, Zhongtiaoshan Tunnel, Yumenkou Tunnel, Dazhongshan Tunnel and Huangbailing Tunnel, as examples. Good application effect has been achieved; therefore the study results can provide reference for followed tunnel construction work.
