摘要
根据潮汐河口河床形态关系,推导了河口治导线放宽率的计算式.利用已有的河口河床形态系数及长江口北槽的有关数据,估算了长江口北槽深水航道治导线的放宽率,且与定床物理模型试验值基本相符.
Based on the morphological characteristics of river-bed of tidal estuaries, a calculation formula for the widening rate of the estuarine regulation line is derived. By use of the morphological coefficients of estuarine river-bed and the relevant data of the north channel of the Yangtze River Estuary, the widening rate of the regulation line of the north deep-water channel of the Yangtze River Estuary is calculated, and the calculation result is in agreement with that of the fixed bed model test.
