Abstract

Grew up in deep buried tunnels are often encounter many unfavorable geological conditions, construction of sichuan songpan project is located in the southern section of minjiang river faulting footwall tunnel on the right side, through the debris flow, landslide and soft rock large deformation DeZhiDai high in-situ stress. By optimizing the project activity fault zone of deformation monitoring in weak rock tunnel, tunnel hole body application advance small duct grouting support; Excavation steps method is used to add temporary inverted arch construction, arch combined hollow bolt, sidewall type bonding mortar anchor, such as the construction process, to effectively control deformation. Provide certain guidance and reference for the similar engineering construction.
