摘要
针对一级消力池内的左侧回流及弯道存在超高与冲击波等问题,通过水工模型试验,以阁壁水库双弯曲溢洪道为例,分析了水力特性,提出了在一级陡槽末端设置折流坎,并在弯道段设置分流墩的方案。试验结果表明,该优化方案有效改善了弯道水流流态、满足泄洪消能防冲要求,并能较少改动现状布置,可供借鉴。
Aiming at the circumfluence in left side of the first stilling basin and the existence of overflow and shock wave in bend,the hydraulic characteristics of two-curved spillway of Gebi Reservoir is analyzed by hydraulic model test.A proposal of a baffle plate set up at the back of first chute and diversion piers at section of curve spillway is presented.Experiment results show that optimized program can not only improve the water flow regime of bend effectively to meet the requirement of energy dissipation,bu...
