为了建立适用于工程上运用的尾矿坝漫顶逐渐溃坝的尾砂出流计算模型，利用细颗粒泥沙的悬移质运动形式，及含沙浑水的流态变化，建立了理论泄流模型。同时，根据溃坝过程的不同时期，给出了适宜的溃坝水流的流量计算公式、尾砂颗粒的沉速计算方法、挟沙力的计算方法以及浑水容重的计算式。该计算模型有助于渐溃泄沙量的预测，是尾矿坝漫顶逐渐溃坝模型的重要组成部分。

In order to set up the calculation model ,suitably applied in the tailings dam overtopping gradually outflow ,the suspended sediment movement forms and muddy waters flow pattern changes are used to establish the theoretical flow model . Meanwhile ,according to the different stages of the process of dam failure ,a suitable flow of dam break water calculation for-mula is given ,as well as tailings particle settling velocity calculation method ,sediment-carrying capacity and muddy wa-ters density calculation formula .The computational model is helpful to predict the amount of gradual dam break sediment and it will become the important part of overtopping gradual tailings dam break model .
