Study on a Development of Ocean Wave Control

从1988年起，我们就开始研究控制海浪的方法.并发展起来。最适合海洋环保的新型防波堤。本研究的主要结论如下：1.通过对潜水平板防波堤性能的研究，提出了一种新的防波堤机理--“逆流式破碎器”。2.本文提出了一个计算最适合于波浪条件的淹没平板尺寸的公式。3.我们已经明确了翼形板的防波堤性能，这是更有用的短波，但不是那么有用的长波。4.我们研制了一种新的防波堤，称为“阶梯式防波堤”，它的防波堤效率在规则波和不规则波下均高于60%。5.我们发现了在浸没板的后区发生流动的现象。流速与入射波高的平方根成比例。这一流动对封闭近海的海水交换是有益的。6.为实际防波堤的设计提供了波浪荷载、系泊张力等基础数据。

We have studied the way to control ocean -waves since 1988. and have developed. the new type breakwater which is the most suitable for an ocean environmental protection. The main conclusions got in this study are summarized as follows: 1. We have made clear the breakwater performance of a submerged horizontal plate and have found out a new mechanism of breakwater which is named "backward flow breaker". 2. We have made up the equation to evaluate the dimensions of the submerged horizontal plate which is the most suitable for an ocean wave condition. 3. We have made clear the breakwater performance of a wing shaped plate, which is more useful for short waves but is not so useful for long waves. 4. We have developed the new breakwater called "Step Type Breakwater", of which the breakwater of efficiency is higher than 60 % for both regular and irregular waves. 5. We have found out the phenomenon in which a flow takes place in the backward region of the sub merged plate. The flow speed is proportional to the square root of an incident wave height. It seems that the flow is useful for the exchange of the sea water in enclosed coastal seas. 6. We have got the basic data such as wave loads on a plate, mooring tension etc. in order to design an actual breakwater.
