摘要
地震波场数值模拟方法中,基于波动方程理论的有限差分法的算法简单且速度快,对于复杂模型有广泛的适用性,能够较为准确地模拟地震波在复杂模型中的传播规律。该文建立一个包含地层起伏和断层结构的复杂模型,利用有限差分法进行波动传播数值模拟,并通过所得叠加剖面验证了该方法的有效性。
In the numerical modeling methods of seismic wave field, the finite difference method which based on the theory of wave equation is simpler, faster and has more applicable for complex model. It can accurately simulate the propagation law of seismic wave in complex model. The complex model is set up which including structure of uneven strata and fault, the propagation of seismic wave is numerical simulated with finite difference method, finally the validity of the method is verified through the stacked profile.
