紫琅湖湖底地形优化设计
|
摘要
为更好指导紫琅湖地形设计,在紫琅湖原有设计方案的基础上,通过合理分配不同水深区域占比,对湖底地形进行优化设计。利用MIKE21流场数值模拟,对紫琅湖湖体风生流、吞吐流进行计算,验证湖体地形的合理性,有利于紫琅湖后续的水系调度和生态系统构建。
In order to better guide the topographic design of Zilang Lake, based on the original design scheme, the optimal design of the lake bottom topography was carried out by rationally distributing the proportion of different water depth areas. By using MIKE21 flow field numerical simulation, the wind-driven flow and huff and puff flow of Zilang Lake were calculated to verify the rationality of the lake topography, which was conducive to the subsequent water system dispatch and ecosystem construction of Zilang Lake.
