Numerical Simulation of excavation and Supporting of Diversion Tunnel for a Hydropower Station

ZHANG Yu-na(Central and Southern China Municipal Engineering Design & Research Institute,Wuhan 430010,China)  
In this paper,the most dangerous section of the diversion tunnel where it intersected with faults and unconformity zones was selected and FLAC3D model was established.Considering the degradation of surrounding rock effected by unloading,the paper analyzed the deformation and stability of surrounding rocks in each step of the tunnel excavation and supporting processes.Results show that the broken-rock zone appears obviously when considering the unloading in tunnel excavation process,suggesting that the rock deterioration has a great influence on the tunnel stability.After adopting efficient supporting measures,the rock deformation and stress have been greatly improved.However,there still exist some local stability problems,such as stress concentrating and deformation prone to occur in faults,which should be paid enough attention.
