摘要
为探究通江口门规模对滨江地区区域防洪的影响,以张家港市为研究对象,利用数值模拟的方法建立区域水文水动力耦合模型,通过设置连通水系、扩建闸门及新增排水泵站三类方案进行分析计算各片区的最高水位。结果表明,通过调整水系、扩建通江口门及新增不同规模的排水泵站,能够有效降低该区域在遭遇100年一遇降雨时的河道最高水位,减轻了区域防洪的压力。研究成果对合理布设城市防洪工程、提高城市防洪能力有借鉴意义。
In order to explore the impact of gate station scale along rivers on the regional flood control in riverside area, the Zhangjiagang City is taken as the research object, and a regional hydrological and hydrodynamic coupling model is established by using the method of numerical simulation. The maximum water level in each area is calculated by setting three schemes of connecting water system, expanding gates and adding new drainage pump stations. The results show that, by adjusting water system, expanding gates and adding drainage pump stations with different capacities, the maximum water levels of river channels in the case of 100-year rainfall can be effectively reduced, and the pressure of regional flood control can be reduced. The research results can be used for references to reasonably arrange urban flood control projects and improve urban flood control capacity.
