Abstract
The diversion and flood discharge sand flushing tunnel of Yudaochuan Reservoir in Gujiao City,Shanxi Province is located in the strongly weathered rock layer on the right bank slope,and the surrounding rock of the tunnel has poor conditions for forming the tunnel.In order to improve the conditions for tunnel surrounding rock formation and enhance the safety of project excavation,through extensive literature reading,comparative analysis,and other methods,it has been found that designing support schemes for the inlet and outlet sections of the tunnel can effectively solve this problem.Based on this,combined with specific project engineering,the selection and implementation strategy of lining support construction schemes for the inlet and outlet sections of the diversion,flood discharge and sand flushing tunnel of Yudaochuan Reservoir were discussed.关键词
