大跨黄土隧道设计与安全施工对策

Design and safety construction measures for large-span loess tunnels

作者根据多年的工程经验,对以往各线黄土隧道设计、施工和塌方情况进行总结和分析,结合郑西客运专线大断面黄土隧道的设计、施工情况,提出了大断面黄土隧道安全施工的对策,希望对拟建的包西、太中银等黄土隧道较多的铁路线有一定的参考价值。

Based on his experience in engineering for years, author of the paper summarized and analyzed the design, construction and collapses of loess tunnels on inland railway lines. Considering the design and construction of loess tunnels on Zhengzhou-Xi＇an passenger-dedicated line, he proposes the design and safety construction measures for large-span loess tunnels which will be helpful for new projects.
