MIKE11模型法和“平湖法”在平原河网区调蓄演算中的对比分析

Comparative Analysis of Mike11 Model Method and“Pinghu Method”in Plain River Network Area Regulation Calculation

河网区水动力条件复杂,为了得到较高精度的调蓄演算成果,该文以东莞市交椅湾新河为例,分别采用Mike11模型法和“平湖法”进行调蓄演算,并从计算原理、来水过程、泵站出流过程等方面分析两种方法计算成果差异,经分析,Mike11模型法较“平湖法”在平原河网区调蓄演算中计算简单,工作量小,同时计算成果更加合理,对工程设计有很好的指导作用。

In order to get more accurate results of regulation and storage,the Mike11 model method and“Pinghu method”were adopted in the regulation and storage calculation of Jiaoyiwan New River in Dongguan,the difference of calculation results between the two methods was analyzed from the aspects of calculation principle,inflow process and outflow process of pumping station.After analysis,the Mike11 model method is simpler than the“Pinghu method”in calculation of regulation and storage of Plain River Network area,and the workload is smaller,at the same time,the result of calculation is more reasonable and has a good guiding function for engineering design.
