Abstract: As a new open-type approach of tidal power utilization, the Dynamic Tidal Power (DTP) technology hasn't been in practical application so far. Taking a research-oriented dam site locating in the south of Bohai Strait as an example, this paper established a mathematical model, and studied the dam type selection, design and construction method. Finally, the conclusions were put forward that the floating caisson should be used for powerhouse section, and the dumped rockfill dam for dike section,worthy reference.

Key words: dynamic tidal power, numerical simulation, dam type selection, floating caisson

摘要： 动态潮汐能作为一种新型的开敞式潮汐能利用方式，目前暂无实际工程应用。笔者从实验分析角度出发，以位于渤海海峡南口的某研究性站址为例，基于数值分析手段，探究了动态潮汐能大坝的坝线、坝长比选方法；对大坝枢纽中的厂房、海堤等主要水工建筑物的设计、施工方案进行了初步研究，提出了厂房段宜采用浮运沉箱结构、海堤段宜采用抛石坝结构的结论，并给出了工程施工方案建议。研究成果对动态潮汐能发电技术后续在我国沿海的实际工程应用具有一定参考意义。
