摘要
对钱塘江涌潮的形成过程作了简单介绍 ,然后利用波浪力经验公式对涌潮压力进行计算并与实测的涌潮压力进行对比和分析 ,得出如下结论 :(1)浅水长波理论和驻波理论可用于涌潮压力的初估 ;(2 )实际的涌潮压力在以波面为零点的静水压力值附近波动 ;(3)涌潮动压力在低潮位偏下的位置达到最大值 ,然后逐渐减小。
Following a brief introduction to the Qian-Tangjiang tidal bore, the empirical formulae and the related tests were presented. The results of numerical calculation and test data were compared and analyzed. And the following conclusion can be drawed: (1) shallow water theory and standing wave theory can be used to estimate the bore pressure; (2) bore pressure fluctuate around the hydrostatic pressure with the zero point at the surface wave crest; (3) the dynamic pressure of tidal bore reaches maximum little below the original tidal level, and decreases with the increase of depth.
