xx新区填海造地工程外护岸口门方案.docx

摘要

通过MIKE软件为围头湾区域建立数值模型，完成对模拟区域水流动力条件的模拟，并通过临时测站的实测水位流速数据对模型进行验证。验证结果良好，模型可以准确反映工程区域的水流动力条件。通过模型对五种宽度口门工况进行模拟计算，对结果加以分析得出各工况下口门流速分布及纳潮量变化，针对工程一期围垦方案，模拟计算龙口合龙过程流速及水位变化，藉此对口门施工方案对水动力条件的影响作出评价。

ABSTRACT

MIKE 21 FM is adopted to build numerical module for Weitou Bay to forecast and estimate the hydrodynamics conditions of the whole waters under research. The results have been confirmed to be reliable for actual project in comparation with actual measurement collected by temporary hydrological stations set in the researched area.The paper simulated five different working conditions which vary in the entrance width.The velocity between the harbor entrance is obtained and the tidal influx before and after the project is calculated.Taking consideration of the first stage of the land reclamation project,The velocity and water level during the progress of cofferdam closure are simulated.Some conclusions are acquired on the impact of project construction on hydrodynamic conditions.

Key words: MIKE;hydrodynamic module; module confirmation;harbor entrance length;cofferdam closure。。。。。。
