水电站漂浮物堆积形态模拟方法探讨

Simulation methods for accumulation patterns floating debris in hydropower stations

针对漂浮物运动特性与堆积形态模拟存在无法同时满足的问题,在分析漂浮物随水流运动特性的基础上,提出漂浮物模拟的相似条件。根据研究重点的不同,可以采用正态模型或小变率的变态模型来模拟漂浮物的堆积形态。从不同模拟材料的试验结果分析,原体漂浮物的运动与堆积采用木条作为模拟材料时,堆积形态更接近实际情况。

With regard to the situation of unable simultaneous satisfaction in the simulation of the movement characteristics and accumulation patterns of floating debris, the similarities for the simulation of the floating debris were proposed based on the analysis of the movement characteristics of floating debris with flows in a reservoir. According to various research objects, normal models or abnormal models with small variability could be. employed to simulate the accumulation patterns of floating debris. The test results from different model materials show that if the weod is employed for the simulation of the movement and accumulation of the original floating debris, the accumulation pattern is much closer to the actual situation.
