溃坝洪水计算溃坝洪水计算evaluation of dam-breaking flood kuiba hongshui jisuan溃坝洪水计算(evaluation of dam一brea-king flood)研究由于大坝失事所造成的水库水体突然泄放而形成的洪水过程及其向上下游传播的专门计算。在溃坝初瞬，坝址处同时发生向上游传播的逆流负波和向下游传播的顺流正波。逆流负波形态如无数元波向上游扩展，相应水体下泄，由于波前水深大f波后水深，即波前速度大于波后元波速度，所以波的外形逐渐展平，水库水面成曲面下降;向下游传播的顺流正波，由于波后的水深大于波前的水深，后波要追赶前波，故形成波前立陡的不连续波，经过一段河槽调蓄和阻力作用，涌波才逐渐坦化，最后消失。图1和图2为溃坝洪水流态的示意描述。阁l溃坝洪水波示意图…丫兰，鄂瓜/坑3断4时间 图2溃坝洪水演进示意图 溃坝洪水计算的目的在于估算溃坝对上下游的影响和可能遭受的损失。主要内容包括:分析研究水库失事时坝址上下游水流状态，计算溃坝洪水的最大流向下游的正波和向上游的负波菠额流量(分别以Q东QB表示)公式如(5)(6)式。。、A，。叼B-一万一叼O十 “卜10尝‘几一Po)(几一Ao’除‘p!一几，(Al一A·’(5)。_AR。昭B一一万叼1十 厂飞l(6)联解两式，即当吼。场时，即得最大瞬溃流量Q，-QB式中A、尸、g分别为过水断面面积、静水压力、重力加速度。其下脚注B、1、0分别表示坝址、上游、下游断面。 瞬时局部溃的计算大坝瞬时局部溃决型式如图4所示。分(a)、(b)、(e)三种情况。由于溃坝口门形式及发展过程均难以事前准确预计，故常作简单假定，一般可假定溃口断面流态类似宽顶堰，而下泄水量补给又满足逆流负波规律，即由宽顶堰(溃口处)的堰流公式如(7)式，和负波流量公式(6)。分别绘制溃口处水深与下泄量关系曲线，其交点即为过水能力和补给水量能力相等之点，相应流量即为所求的溃水最大流量Qm，其相应的水深为溃口水深ko Q。=规b召么叠(HI一a)”‘2(7)式中观为宽顶堰系数，H;为溃前水深，b，a见图4。
