【摘要】 安谷电站厂房尾水和船舶通航共用一长约10 km的尾水渠,电站增甩负荷产生的非恒定流是影响船舶通航的一个重要因素。利用物理模型对电站非恒定引起的长尾水渠水位和流速过程线进行实时测量,总结了非恒定流引起的最大水位变率、最大流速及相应比降、最大比降及相应流速,并计算了最不利工况下船舶有效推力和航行阻力。研究表明:电站增甩负荷幅度较小时,船舶可以正常航行于长尾水渠中。更多还原

【Abstract】 In Angu Power Station on the Dadu River,the navigation pass is about 10km-long tailwater channel,so the unsteady flow of power stations is a most important factor in navigation.The water-height graph and velocity graph of long tailwater channel are real-time measured by model tests,the maximal water-height variability,maximal velocity and corresponding gradient,maximal gradient and corresponding velocity are obtained,and the ship resistance and effective push are calculated,then the results indicate that ship craft can navigate on the tailwater channel,as long as the power station add-and-subtract load has a narrow range.更多还原
