【摘要】 用加里津方法推导了二维线性流变体内波传播的有限元方程，方程内包含了边界项，使得处理人工边界影响有较好的结果．同时考虑了其它一些因素，例如，吸收介质、爆炸源、自激自收等．实例表明，作者在仿真性方面的努力是成功的，计算的垂直地震剖面理论地震图质量比较好，结果也显示了地表低速层对地表水平记录剖面的干扰．更多还原

【Abstract】 In this paper we use Garlerkin’s method to derive 2-D finite element equation for seismic wave propagation in media with linear rheological property. Different from the equation derived with variational method and with Garlerkin’s method by others, the boundary terms are involved in our equations. It makes us to use a newmethod to process artifical boundary effect and has good efficiency. We also considers some factors to get a real-like synthetic seismogram, include: media with obsorption, explosive source, common souce/receiver display, etc. Case’ s results showthat we are successful in getting reality of synthetic seismogam, the calculated VSP has good quality. Sigle source records also show how surface low velocity layers disturb the surface record profile.更多还原
