地震带下螺旋隧道全断面深孔预注浆施工技术研究

Full-section Deep Hole Pre-grouting Construction Technology of Spiral Tunnel Under Seismic Zone

因地震带下复杂地质螺旋隧道工程状况复杂,对技术要求更加严格,控制隧道施工引起的地层变形和保障隧道的施工安全尤为重要。通过理论研究与现场施工,研究施工工序与技术要点,并得出结论,可为类似工程提供借鉴。

Due to the complex conditions of complex geological spiral tunnels under earthquakes, the technical requirements are more stringent. It is especially important to control the formation deformation caused by tunnel construction and ensure the safety of tunnel construction. Through theoretical research and on-site construction, the construction process and technical points are studied, and come to the conclusion, hope to provide reference for similar projects.
