摘　　要：在隧道工程建设过程中,常遇见滑坡、喀斯特和软土等不良地质条件。每种不良地质都会对隧道施工构成一定的安全隐患。文章从滑坡地质角度出发,结合实际隧道项目浅埋、大断面等特点,研究隧道预加固组合技术对滑坡地带的加固能力,分析预加固组合技术对滑坡地段隧道施工的变形控制能力。通过隧道施工现场监测,可知采用注浆预加固、超前管棚支护和超前小导管的组合预加固技术应用效果良好,能有效控制滑坡地带浅埋大断面隧道的施工变形。In the process of tunnel engineering construction,adverse geological conditions such as landslide,karst and soft soil are often encountered.Each kind of adverse geology will pose a certain safety hazard to tunnel construction.From the perspective of landslide geology,combined with the shallow-buried and large-sectional characteristics of actual tunnel project,this paper studies the reinforcement ability of tunnel pre-reinforcement combination technology to landslide zone,and analyzes the deformation control ability of pre-reinforcement combination technology to tunnel construction in landslide section.Through the monitoring of the tunnel construction site,it can be seen that the combined pre-reinforcement technology of grouting pre-reinforcement,advanced pipe shed support and advanced ductule has a good application effect,which can effectively control the construction deformation of shallow-buried large-sectional tunnel in landslide zone.
