The System Construction of Numerical Simulation of Tsunami Excitation and Responses on Coastal Structures

在本年度，我们的研究主要集中在以下几个方面：1、开发了浅海系泊浮式结构物海啸波浪激振力预测方法的数值分析系统。2、通过波浪水槽试验，研究了系泊浮式结构物在海啸作用下的响应特性。建立了系泊浮式结构物在模拟海啸作用下的响应仿真系统。在水深超过30m的情况下，海啸对浮式结构物系泊张力的影响较小。此外，由海啸引起的系泊张力与由最大风浪力引起的系泊张力在同一数量级。

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.
