摘要
本文以长江左岸某拟建H码头工程为例,在MIKE软件平台上建立H码头河段内二维水流数学模型,对H码头兴建前后河段内水流的流态、壅水高度以及流速、流向进行了计算分析研究.H码头建成后,河段内的水位雍高值不超过0.01m;水流流速和流态均无明显变化,且其受影响范围都介于工程上游400m至下游800m范围内.研究结果表明该H码头工程的建设对其所在河段的河势及行洪不会产生明显不利影响.
A 2Dflow mathematical model,prototyped from a planned H wharf in the Yangtze River,was built in the software MIKE.Simulations and investigations were conducted with respect to the flow patterns,backwater and velocity inside this model,aiming at a detailed evaluation of the impacts on the flood discharge due to the construction of the H wharf.The results show that after the H wharf construction,the values of backwater in the whole region are less than 0.01m;water velocity and flow patterns have no obvious change;the affected region range is within the 400 mupstream to 800 mdownstream with respect to the H wharf’s location.It is indicated that the construction of the H wharf will have no obvious impacts on the flood discharge and flow patterns in this river reach.
