卡群一级电站泄水陡坡于１９９５年底建成运行后，由于弯道体型设计不合理，当泄水流量为２８ｍ３ｓ－１（设计流量为６０ｍ３ｓ－１，加大流量为７０ｍ３ｓ－１）时，弯道水流已甩出凹岸边墙，而弯道凸岸基本上处于无水状态。对此，我们进行了模型试验研究。经多种修改方案试验比较，其中在陡坡段设置消能栅、弯道段设置导流消能板（简称综合式）的方案，既能较好地控制急流弯道水流流态，消除下级陡坡中水流折冲现象，又不改变原来弯道体型，节省了工程量。本文除对不同方案的体型布置及流态作简述外，着重对综合方案的水力特性及效果作分析和阐述
Due to the unreasonable curve body design, when the drainage flow is 28m3s-1 (designed flow rate is 60m3s-1 and flow rate is increased to 70m3s-1) after the steep slopes of sluice discharge at the card group level are completed and put into operation at the end of 1995, Road water has been thrown out of the concave side wall, while the bend is basically in a state of shore. In this regard, we conducted a model test study. Comparison of a variety of modifications programs test, in which steep slope section set energy-saving grid, curved section set diversion energy dissipation board (referred to as the integrated) program, both to better control the jet stream flow pattern, eliminating sub-steep slopes The phenomenon of inflow of water, without changing the original curve body, saving the amount of engineering. In addition to the different layout of the program size and fluid state to give a brief, the emphasis on the comprehensive program of hydraulic characteristics and effects for analysis and elaboration
