岩滩溢流坝应用宽尾墩联合消能技术的机理、效果、效益与启迪

Mechamism, Effectiveness, Benefit and Enlightenment on the Combining by Application of Flaring Gate piers Combining Energy Dissipation on Yantan Spillway Dam

宽尾墩联合消能技术，是传统二元水流消能方式迈进三维空间消能简单而有效的工程措施。通过岩滩水电站具体应用，并经过工程运行实践表明，可以兼收工程。

The technic of combining energy dissipation by means of flaring gate piers is a simple and effective measure for transition from two dimensional energy dissipation into three dimensional one.Through the application and practice on Yantan project the profitability and engineering economics can be proved.
