| 摘 要： | 为优化位于广州市白云新机场配套综合开发区范围内的社工坑整治方案,采用MIKEFLOOD耦合一维MIKE11和二维MIKE21水动力模型对铁山河流域进行洪水危险分析,模拟流域遭遇不同重现期洪水时的淹没状况。洪水危险分析结果表明,当遭遇20年一遇设计洪水时,社工坑流域淹没面积达4.03 km2,最大淹没水深达0. 93 m,淹没区域主要位于开发强度较大的中下游地区,而干流铁山河下游段尚有一定行洪能力;提出新建两条支涌将社工坑中下游洪水引入铁山河下游的整治方案。

| Abstract: | In order to optimize the regulation scheme of Shegong River located in the comprehensive development area of Guangzhou Baiyun international airport, a flood hazard analysis for the Tieshan River watershed was made by coupling one-dimensional MIKE11 and two-dimensional MIKE21 hydrodynamic model with the MIKEFLOOD to simulate the basin inundation situations in the case of the floods in different recurrence periods. The results show that the area of flooding inundation range in Shegong River basin is 4.03km2, the maximum inundation depth is 0.93m, and the inundated area is mainly located in the middle and lower reaches with strong development intensity, while there is a certain flood discharge capacity in the lower reaches of Tieshan River when encountering the flood with a return period of 20 years. A regulation scheme that two new branches should be built to pit the flood in the middle and lower reaches of Shegong River into the lower reaches of Tieshan River was drawn up. |
