The invention provides a turbulence chamber stilling pool which is arranged at a spillway or a tunnel spillway outlet, and is composed of a gradual expanded counter-slope section, a turbulence chamberand a tail ridge which are sequentially connected in a water flow direction, wherein the gradual expanded counter-slope section is connected with an upstream spillway or tunnel spillway outlet; the gradual expanded counter-slope section is composed of a slope surface bottom plate and side walls in symmetry on both sides of the bottom plate; a channel which is gradually expanded in the water flowdirection is formed; a falling ridge is arranged at the outlet of the tail end of the channel; the falling ridge is connected with the turbulence chamber downwards; the turbulence chamber is composedof a bottom plate and two arc-shaped side walls in symmetry on both sides of the bottom plate; the width of the turbulence chamber is gradually increased and gradually reduced from the outlet of the gradual expanded counter-slope section till the turbulence chamber is connected with tail ridge. The stilling pool is particularly applicable to energy dissipation by bottom flow in large single widthflow spillway or a tunnel spillway outlet of a medium/high water head hydropower station, and the problem of atomization caused by flip trajectory buckets can be avoided.
