摘要
通过建立基于有限体积法的大小嵌套的潮流数学模型,在对现场实测资料进行验证的基础上,对倒运海水道整治方案进行了水动力模拟计算,从动力场的角度分析了工程方案的效果。结果表明:工程实施后对水流的影响主要集中在工程附近水域,不会改变大范围水域的水位、流速以及涨、落潮的潮流特性,故工程方案对倒运海水道水动力场影响不大,可以达到工程的治理目标。
By using the finite volume method, the nested numerical model of tidal flow was established, based on the on - site verification of the measured data. Then the channel regulation program of Daoyunhai waterway and the hydrodynamic field were simulated. And the effect of channel regulation program was analyzed in the view point of dynamic field. The results show that after implementing the project, the effect of water flow is focused on the waters near the channel regulation. It does not change the wide range of water level, flow velocity as well as rise, ebb tide character- istics. So, the project program has little effect on the hydrodynamic field of Daoyunhai waterway, and it can achieve the Droiect goal of contr,I.
