The purpose of opening the orifice was to sluice. The influence of fluctuating pressure upon the dam was another problem which was concerned by engineer. The paper analyzed Shuangkoudu masonry arch dam. The result indicated that the dam natural frequencies which consider the dam and the reservoir water interaction have great different from the preponderant frequencies of fluctuating pressure, the dam's first rank of vibration was far away from the high energy region of the fluctuating flow, so the sympathetic vibration would not take place.
坝身开设孔口主要目的是为了泄洪,泄洪时水流脉动压力对坝体结构动的影响是设计人员关心的另一课题,论文针对双口渡浆砌石拱坝进行了分析,研究结果表明:在考虑坝体一库水相互作用时坝体自振频率和水流脉动压力的优势频率相差较大,坝体的一阶振动远离脉动水流的高能量范围,二者不会发生共振。
