摘要: 介绍了在通用有限元软件MSC.Marc中实现"分裂节点法"地震位错模拟,并使用此方法验算走滑断层震例引起的同震位移场。结果表明,该方法精确、简单、有效,也可以很方便地移植到其他具有二次开发接口的有限元软件中。Abstract: This paper discusses the implementation of the "splitting nodes" technique in the MSC.Marc soft ware. Adopt this technique, coseismal displacements resulted from strike-slip fault are calculated and compared with the analytic solutions. The technique described here offers a simple and efficient method of introducing faults into finite element computations, and can be implemented in other FEM soft through the user subroutine.
