The invention discloses a novel sluice bucket type flow-dividing and energy-dissipation scour prevention technology. The technology comprises five parts, i.e., the overall design thought, the type selection of a section simulating hydraulic model, the verification of an integral simulating hydraulic model, the observation of an original model, and the comparison of economic technology, and the like. The design of the invention has eight most important key parts, i.e., the frontal edge width B1 of a pier, the top width B2 of a tail end, the bottom width B3 of the tail end, the inverted arc radius R of the upstream face of the pier, the flip shot angle Theta, the pier height P, the number of the pier, and the top space B4 between the tail ends of the piers, and the like. The design method of the sluice bucket type flow-dividing and energy-dissipation scour prevention technology is divided into two major parts, i.e., the body form design and the distribution of the piers. The bucket type flow-dividing pier designed in the way is characterized by low downstream water level, high energy consumption rate in ordinary flow flood discharging working condition, small stilling pool depth, short pool length, less workamount, low investment, and the like.
