摘要
针对马斯京根洪水演算模型的近似性问题,用曲线积分法改进了原模型中时段流量的简单算术平均值法,并利用连续性空间优化问题的蚁群算法对改进的马斯京根洪水演算模型进行参数最优估计,使演算流量更加接近实际。
In light of the approximation of Muskingum flood calculation model, an improving model on average flow within prescribed time in flood calculation is presented using curve integral instead of general arithmetic mean. By making use of the ant colony algorithm in the continuous space optimization problems, the flood calculation problem of parameter estimation of improved Muskingum routing model is solved. The results of the computer simulation show that the improved Muskingum routing model is valid and practical, and it is suitable for solving the flood calculation problems.
