摘　　要：针对溢流坝段在正常高水位时,由于闸门的启闭导致大坝承受水压力发生变化,从而引起库水位与水平位移关系曲线不连续情况,在建立水平位移混合模型时引入了分段函数和阶跃函数。计算结果表明,计算方法合理有效。The water pressure on dam will be changed owing to the strobe turned off or on when the dam is in normal water lever condition,which results in the curve between reservoir water lever and horizontal displacement discontinuous. Therefore, piece wise function and step function are used to erect the mixed-model of horizontal displacement and the outcome shows that the method is reasonable and effective.
