摘　　要：利用ABAQUS软件平台,建立分层土体的动力有限元模型,边界条件分别采用透射边界,无限元边界,固定边界和远置边界,分析比较表明:基于透射边界理论和ABAQUS软件DISP子程序施加的透射边界,获得的数据结果更接近于远置边界条件。Used ABAQUS software platform,the dynamic finite element models are established of the layered soil,and the boundary conditions are described as the transmitting boundary,infinite element boundary,and far fixed boundary,respectively. Through the analysis and compari-son show that based on the theory of transmitting boundary and DISP subroutine of ABAQUS software,the data obtained from the results of trans-mitting boundary is more close to the far boundary conditions.
