| Abstract: | The paper has analyzed the emergency repair processing scheme and successive reinforcement treatment scneme for surface subsidence by illustrating the collapse accident of Dananshan sewage interception tunnel of Shenzhen Hewan Sewage Interception and Discharge （Phase 2） Project and starting with the engineering geological conditions of the roof at the collapsed place. After the surface reinforcement and support reinforcing treatment inside the tunnel for nearly one month, the tunnel excavation has successfully passed through the collapse area, which has obtained good treatment effects and provided reliable guarantee for construction safety. |
