基于MIKE11的九江片水闸排水作用分析计算

Analysis and Calculation of Drainage Effect of Jiujiang Sluice Based on MIKE11

以佛山市南海区九江片水闸排水作用分析计算为例,考虑围内所有水闸联合排水,应用MIKE11模型计算水闸联合排水时围内河涌的水位变化过程,从河涌最高水位、最高水位持续时间和水闸排水总量不同角度分析水闸的排水作用,对不同闸宽方案进行对比分析,为片区水利工程规划调整提供依据。经实例验证,MIKE模型能较好的模拟水闸联排情况时河涌水位变化过程,不同闸宽方案的对比分析结果符合片区实际,可为河网地区的水利工程规划调整提供参考和思路。

Taking the analysis and calculation of the drainage effect of Jiujiang Sluice in Nanhai district of Foshan city as example,considering the combined drainage of all the sluices in the enclosure,the MIKE11 model is used to calculate the change process of the water level in the enclosure when the sluices are combined drainage.The drainage effect of the sluice is analyzed from different angles of the highest water level,the duration of the highest water level and the total drainage volume of the sluice,and the different width schemes are compared and analyzed,which provides the basis for the planning adjustment of regional water conservancy projects.The example shows that MIKE model can better simulate the process of water level change when the sluices are connected and discharged.The comparative analysis results of different sluice width schemes conform to the actual situation of the area,which can provide reference and ideas for the planning and adjustment of water conservancy projects in the river network area.
