摘要
为分析消力池方案和急流护坦方案两种消能方式在山区河流中小型闸坝工程上的适用性,以浦西水电站为例,在1∶40的模型上对比分析了两种消能方式在水流流态、河道流速、下游冲刷程度、汛期排沙等方面的异同。结果表明,急流护坦消能方案在各种运行组合下均能获得稳定的流态,且便于汛期排沙,只要措施得当,下游冲刷程度能得到有效控制,较消力池方案更适用于山区河流中小型闸坝工程。
In terms of energy dissipation structures, stilling basin and torrent apron are mostly applied in small or medium-sized sluice dam on mountain river. In order to analyze the applicability of these two ways of energy dissipation, hydraulic model tests were done with model scale of 1 ： 40. Hydraulic characteristics such as flow pattern, velocity distribution, downstream erosion and sediment flushing were obtained. The results show that the torrent apron mode can obtain stable flow pattern in different operation combinations and is convenient to flush sediment. As long as the appropriate measures, downstream erosion can be effectively controlled. And torrent apron mode is more suitable for small or medi- um-sized sluice dam on mountain river.
