摘要：Transforming diversion tunnel to spillway tunnel is common in engineering .A kind of ogee spill way tunnel is studied in this paper , in which the flow field is very complicated .Through simulating turbulence through RNG k~ εmodel and standard wall functions and tracking the free surface through GEO-construct method of VOF model ,a 3d flow field numerical simulation for a tunnel spillway was developed under the design flood level .The results of the water sur-face ,bottom pressure and lengths of aeration cavity were compared and analyzed with the model test data which were in good agreement .So the solution data can be used for engineering design .
