数值模拟技术在青草沙水库规划设计中的应用

Application of numerical simulation in planning and design of Qingcaosha Reservoir

针对潮汐河口水库在规划设计阶段常见的问题,以位于长江口南北港分流口水域的青草沙水库工程为例,介绍了数值模拟技术在河口地区水库规划中的应用情况。重点研究了数值模拟技术在水库堤线布置、水库规模确定、库内主要水工建筑物平面布局等方面的应用,从研究思路、模型选择、关键技术点及主要成果等方面进行了归纳分析。研究成果可为今后同类工程提供参考与借鉴。

For solving the problems in the design and planning of a tidal estuary reservoir, we illustrate the application condi- tion of numerical simulation software in construction of Qingcaosha Reservoir, a reservoir located at the junction area of Naugang waterway and Beigang waterway in Yangtze Estuary. We focus on the application condition in reservoir dyke layout, determination of reservoir capacity and layout of other hydraulic structures, and summarize the application experiences from aspects of research ideas, software selection, key techniques and the main results. The research results can provide references for other tidal reser- voir construction.
