摘　　要： 底流消能工消力池平面布置大多采用等宽直线型,但在弯曲河段采用直线型消力池将大大增加岸坡开挖工程量。通过水工模型试验,研究了德党河水库曲线型消力池内的水流特性及存在的问题,对设计方案进行优化,并进行了模型实验,实验表明采用跌坎式曲线型消力池能有效解决折坡段容易出现的空蚀现象和消力池内水流折冲明显等问题,且消能效果明显。 The underflow stilling basin mostly has a straight-line shape with equal width,but it renders much more excavation at bend river course.Hydraulic model test was conducted to study the flow characteristics and existing problem,as well as the optimized design of the curved stilling basin at Dedanghe Reservoir.The results of test demonstrate that cavitation liable to occur at the gradient change section and swinging flow within stilling basin are effectively vanished when the curved stilling basin is connected with falling sill at upstream position.
