结合鱼剑口电站坝下消能防冲试验研究成果，对低坝枢纽宽尾墩的水流特点、掺气特性、宽尾墩对大坝泄流能力和坝面压力的影响以及宽尾墩的消能效果等问题进行了初步探讨，提出了合理地使用宽尾墩结合辅助消能设施可有效地解决坝下覆盖层深，地质条件差，抗冲能力弱的低坝枢纽的消能防冲问题，从而为具有低水头，大单宽流量，低佛氏数特点的低坝枢纽泄洪消能开辟了一条新途径，可供有关低坝枢纽设计与试验工作者借鉴与参考 Based on the research results of energy dissipation and erosion control at the dam of Yujian Power Station, the influence of water flow characteristics, aeration characteristics, discharge capacity of dam tail and dam surface pressure on flaring piers of low dam and the effect of flaring pier Energy dissipation effect and other issues were discussed. The reasonable use of flaring pier combined with ancillary energy dissipation facilities can effectively solve the energy dissipation of low dam junctions with low overburden depth, poor geological conditions and weak anti-impulse capacity So as to open up a new way for flood discharge and energy dissipation of low dam hubs with low head, large single-wide flow rate and low Fog number, which can be used for reference and reference by design and test workers of low dam
