摘要
汉江石泉枢纽运用后,其下游河道受日调节影响,水位陡涨陡落,碍航情况严重。文中建立了一维数学模型,利用汉江石泉水文站至汉王城68 km河段非恒定流资料对模型进行了验证,计算结果表明该模型稳定性好、准确可靠。选择石泉水文站若干个下泄过程组合概化了一种新的下泄过程,该下泄过程满足河道最低通航保证率的要求。
The lower reach of the Shiquan hydroelectric Hanjiang River came into operation. The water level steeply station is affected, after the Shiquan hydroelectric station in rises and steeply drops, and it is very serious for the river to navigate. The one - dimension mathematics model is built, and is verified by the non - constant flow data from the Shiquan hydrologic station to Hanwangcheng, the result shows that the stability is good and the accuracy is high. A new release discharge process of the Shiquan hydroelectric station is generalized from many discharge processes of that, and which can be satisfied with the requirement of the guarantee rate of designed minmum discharge.
