| 摘 要： | 推导了地震海啸波传播的理论方程,并时局地地震海啸情况下的理论方程进行了求解.基于Boussinesq方程出发,建立了二维局地海啸渡传播数学模型;对局地海啸进行了数值计算,计算方法采用有限差分方法.差分格式采用交替方向隐格式,即ADI方法.利用该模型对发生在台湾海峡的一次地震海啸进行了模拟计算.将计算结果与理论方程的计算结果以及实际情况进行了对比.计算结果较好.为局地海啸波传播提供了一种模拟方法.

| Abstract: | The solution of the water surface of the wave equation caused by earthquake is derived,which is the theoretical equation of earthquake tsunami and it is the theoretical equation of earthquake tsunami and then is applied to calculating the local tsunami.Based on the Boussinesq equation,a 2D local tsunami wave propagation mathematical model is built and the local tsunami is simulat-ed using this model.Applying the local tsunami numerical calculation mode,an earthquake tsunami which happened in the Taiwan Stra... |
