摘要
通过局部动床模型试验 ,研究了石梁河水库新老泄洪闸闸下河床冲刷特性 ,分析了枢纽运行方式、出池水流的流速流态等因素对闸下冲刷的影响 。
Through local dynamic bed model test,the scour characteristics are studied of river bed under the new and old sluice gates of Shilianghe Reservoir;main factors are analyzed such as the operation mode of the project that influence the scour under the sluice gats;reasonable scour lessening mode of united operation of the new and lod sluice gates is suggested;and efficient engineering measurements are proposed for lessening scour,such as distorting side wall in the stilling basin and baffle blocks of horseshoe shape on the secondary dropoff.
