边界条件对多沙河流电站前漏斗形态的影响

Influence of Border Condition on Funnel Shape in Front of Hydroelectric Station on Sediment-laden River

电站前漏斗形态影响因素较多 ,其中边界条件到目前为止是人们研究较少的影响因素。通过搜集历年来黄河小浪底水库及三门峡水库的试验资料 ,分析得出 ,边界条件是一个不可忽视的影响因素 ,通过改变某些边界条件可对多沙河流电站前漏斗的形成产生积极的影响 ,并可增大电站前的漏斗范围。

The formation and shape of funnels i n front of hydroelectric stations located on sediment-laden rivers could be inf luenced by lots of factors, among which the border factor has been less studied . The author collected various test data from the hydroelectric stations at the Xiaolangdi and Sanmenxia reservoirs and through detailed analysis found that the conditions of border could play an important role in the formation of the funn el. It is concluded that changing some of the border conditions can exert positi ve effects on the formation of the funnel and enlarge its range.
