河岸码头建筑物势必导致其上游水位壅高及对码头附近水流流态产生影响。以汉江沙洋河段为对象,通过定床概化物理模型试验研究了码头建筑物对河道水位与流速场的影响。并基于能量平衡原理,采用河道恒定非均匀流水面曲线基本方程,结合物理模型试验资料,计算了码头建筑物附近的水位变化值,并提出了码头建筑物产生的水位壅高值的计算方法。

A dock construction built on a river bank causes naturally the water level upstream to rise and influ ences the local flow pattern.Through an illustration of generalized fixed bed model simulating Shayang river stretch on the Hanjiang River,the influences of dock construction on water levels and velocity field have been investigated in the model test.On the basis of the principle of energy conservation,and using the basic equation of steady nonuniform flow water surface profile and combining with the test data,the calculation method for water level caused by dock construction is proposed,and the variation values of water levels near the Shayang dock construction are calculated. 
