Abstract:It’s important to choose an appropriate type of energy dissipation in discharge structures .Here ,three kinds of dissipaters ,which were shock pier ,stairs and stilling basin were designed to dissipate energy in the downstream of the water conveyance tunnel in a hydraulic project .To study the effect of the three energy dissipaters ,model test was adopted to research the energy dissipation rate in this paper .Two conditions of energy dissipations were calculated ,including the combination of shock pier with stilling basin and the combination of shock pier ,stairs and stilling basin .The test results prove that the combination of the three energy dissipaters is effective in eliminating energy of flood flows when they reach the stilling basin of the water conveyance tunnel ,thus reducing the scour to the waterbed and river banks in the down-stream and protecting the project for it to operate safely .
