摘　　要：通过总结多项工程T型墩消力池的研究成果和原型观测,对T型墩的水力特性,特别是池内流态及尾水适应条件进行了分析,与平底消力池的池长、池深及消能率进行了对比,并通过原型观测进行了验证,结果表明:T型墩消力池结构紧凑,消能效率高,消能效果良好以及尾水波动小、经济效益好,是一种适合于中、低水头的较理想的消能形式。By summarizing the research rusults of T-shaped pier stilling pools,along with prototype measurements,especially the fluid state in the stilling pool and the kind of construction well adapted to the tailwater,and compared to a flat bottomed stilling pool＇s length,depth and rate of energy dissipation,using prototype measurements.The result shows that the T-shaped pier stilling pool has a more compact structure,a higher rate of energy dissipation and hence a better effect on energy dissipation,along with a smaller wave in the tailwater and higher economic returns.It is an effective energy dissipation form and is well suited to middle or low water head dams.
