摘要 起伏地表地震波数值模拟中,如何选择适合地表的数值计算方法以及更好地实现起伏自由边界条件是2个关键问题。为此,就前一个关键问题所涉及的方法、原理以及发展状况进行了详细的阐述分析;而对后一个问题,就近年来发展的主要实现方法进行了详细的论述。目的在于选择适当的实现方法解决相应的问题,以达到满意的模拟效果。 Numerical simulation of seismic waves from irregular topography is a hot issue. In this area there are two key aspects controlling the success of the simulation. The first is how to select appropriate numerical simulation method. The second is how to realize free boundary conditions. This paper reviewed the first issue in terms of methodology, principles, and current situations and discussed in detail the realization methods for the second issue.
