摘要
目前计算拱坝温度荷载时上游水位固定在正常蓄水位,但实际库水位是变化的,由于水温与气温的巨大差异,上游水位的变化对拱坝温度荷载有较大影响。笔者提出了按照上游实际运行水位计算拱坝温度荷载的方法,计算结果表明,其影响比较大。
In the present method for computing temperature loads on arch dams, the water level in the reservoir is fixed at the normal high water level Practically the water level of the reservoir varies continuously in a year. Because the temperature of water is different from that of air, the variation of water level of upstream side strongly influencies the temperature loads on the arch dam. A new method is proposed to compute the temperature loads on arch dams taking into account the variation of water level in the reservoir.
