采用先进的、科学的网络进度控制计算，比较洞挖和明挖两方案对工期的影响，选择能保证工期的洞挖方案。并在洞顶覆盖厚只有3．38m的湿陷性黄土洞段运用新奥法施at原理，采用地面锚固和超前锚固等方法，成功地完成了隧洞施工任务。
The use of advanced and scientific network schedule control calculation, comparison of the two projects digging and digging the impact of the project duration, choose to ensure the project schedule digging program. In addition, the tunnel construction task was completed successfully by covering the collapsible loess section with a thickness of only 3.38m on the top of the tunnel using the New Austrian Fa method at ground level, using ground anchors and advanced anchoring methods.
