摘　　要：分析了二通道钱塘江出口处水域设计条件下涌潮高度与潮差、低潮位的关系,采用低潮位下50 a一遇的涌潮高度作为船闸闸门涌潮作用力试验的边界条件,得到船闸闸门所受的涌潮作用力和分布特征,涌潮对船闸闸门的最大作用力发生在低潮位附近,引航道喇叭形的出口将会加大涌潮对闸门的作用力。Based on the analyzed results between the tidal bore height and tidal lower level at the outlet of Jinghang Great Canal crossing the Qiantang River, tidal bore pressure and its distribution at the gate of the ship lock have been found through tidal bore flume experiment. The gate＇ s maximal pressure is near the tidal lower level. The funnel - shaped outlet of ship lock will increase the tidal bore pressure on the gate.
