摘要
为分析花博园地区水系整治工程的除涝效果及影响,利用MIKE11软件中的水动力模块基于一维水动力原理建立花博园片区水动力模型对片区除涝效果及影响进行计算分析。计算结果表明:工程实施后,除涝期间花博园周边水系最高水位变化幅度在-0.003 m~0.012 m之间,大部分河道较工程前略有上升;崇明岛大片水位上升约0.006 m,影响在毫米级。在超标准台风条件下,园区内防汛除涝有一定的风险,但是风险水平不高,研究可为类似水系整治工程提供参考。
To evaluate the drainage effectiveness and impact of the water system rehabilitation project in the Huabo Garden area,a one-dimensional hydrodynamic model was established using the hydrodynamic module of MIKE11 software.The model was used to perform calculations and analysis based on one-dimensional hydrodynamic principles.The results show that after project implementation,the maximum water level variation in the surrounding water system during drainage events ranged from-0.003 m to 0.012 m,with most river channels experiencing a slight increase compared to pre-project conditions.On Chongming Island,the water level rose by approximately 0.006 m over a large area-an effect at the millimeter scale.Under extreme typhoon conditions,there is a certain degree of flood drainage risk within the park,though the risk level remains low.The study provides a reference for similar water system rehabilitation projects.
