In the present year, our researches were curried out the following subjects;1,Development for the numerical analysis system on the prediction method of Tsunami wave exciting forces on floating structures in shallow sea.2,To clarify the characteristics of responses on moored floating structures induced by tsunami by using wave tank experiments.3,To establish the simulation system of responses on moored floating structures by using simulated tsunami.From the results of above research, we could get the following conclusion as;In the case of over 30m water depth, the influences of tsunami on mooring tensions of floating structure are small. Also, the mooring tensions induced by tsunami are same order to the mooring tensions induced by maximum wind wave forces.

今年以来，我们主要开展了以下工作：1、浅海海啸波浪对浮式结构物激振力预测方法数值分析系统的开发。2、通过造波池实验明确海啸对系泊浮式结构物的响应特征。3、建立模拟海啸对系泊浮式结构物响应的模拟系统。 通过以上研究，我们可以得到以下结论：在水深超过30m的情况下，海啸对浮式结构系泊张力的影响较小。此外，海啸引起的系泊张力与最大风浪力引起的系泊张力具有相同的量级。
