    摘要:

    为研究吉安市游船制造及维修工程对研究区域河势及防洪的影响,本文采用MIKE21 软件建立二维水流数学模型,结合河道演变分析、水文分析计算以及工程河段水文特性、工程地质等资料分析,对工程的修建进行防洪综合评价。研究结果显示:工程兴建对河道壅水影响不大,水位变化主要集中于工程附近区域。工程引起水位壅高最大值为5.78cm,在上游局部区域,受开挖影响水位有所降低,降低最大值为10.20cm。引起流速减小最大值为0.85m/s,流速增加最大值为0.53m/s;工程河道将继续保持现阶段基本稳定的整体河势演变发展趋势。在来水来沙条件不发生明显改变的条件下,河段岸线在未来一定时期内仍将保持相对稳定。

    Abstract:

    In order to study the influence of Ji′an cruise ship manufacturing and maintenance project on the river potential and flood control in the study area, this paper uses MIKE21 software to establish a two-dimensional mathematical model of water flow, combined with the analysis of river evolution, hydrological analysis and calculation, as well as the analysis of hydrological characteristics of the engineering river section, engineering geology and other information, to make a comprehensive evaluation of the construction of the project for flood control. The results show that the construction of the project has little influence on the river congestion, and the water level changes mainly concentrate in the areas near the project. The maximum value of water level congestion caused by the project is 5.78 cm; in the upstream local area,the water level is reduced by excavation, and the maximum value of reduction is 10.20 cm; the maximum value of reduction of flow velocity is 0.85 m/s, and the maximum value of increase of flow velocity is 0.53 m/s; the river channel of the project will continue to maintain the development trend of the overall river potential which is basically stable at this stage. Under the condition that the water and sand conditions do not change significantly in the future, the river bank will remain relatively stable in a certain period of time in the future.
