摘要
为右江那吉枢纽下游88 km河段建立了正交贴体坐标系下航道水流二维数学模型,在网格布置上,模型根据河道特点,对汊流河段进行分汊处理,提高了汊道水流的计算精度。模型建成后,首先利用实测资料对模型进行了率定,然后对河道碍航特性进行了分析,最后,给出了满足设计要求的整治措施和具体整治效果。
A 2-D current mathematical model is established for channel regulation of 88 km reach from Naji to Yuliang of Youjiang River. The calculated result is more exact by special treatment to the grid on branched streams. Firstly, the model was checked with measured data. Then, the characteristics obstructing navigation were studied. And finally, the regulation measures and results meeting the requirement of design were presented.
