摘要： 基于MSC.Marc软件的操作平台，利用二次开发编程接口USER SUB.HYPELA，开发了土体等价非线性粘弹性动本构模型的子程序。选择广州某个典型软弱场地为研究对象，对该场地的地震反应进行二维有限元分析，与专业的土层地震反应分析软件SHAKE91计算结果进行对比，验证了该模型二次开发的准确性和可用性，可有效用于地震非线性分析。

Abstract: An equivalent nonlinear visco\|elastic constitutive model of soils is developed by the use of secondary development programming interface function, USER SUB.HYPELA, on the MSC.Marc software platform. A typical soft soil site in Guangzhou is selected for the study. The site specific seismic spectrum is analyzed by a two\|dimensional finite element analysis (FEA). To verify the accuracy and reliability of the suggested constitutive model, the result compares well with the results from SHAKE 91, the widely accepted software for the seismic reaction of overlying soils.
