摘　　要：利用有限元通用分析软件ABAQUS的用户子程序,实现Duncan-Chang模型的开发;同时利用热传导模块进行渗流分析。以此对某土石坝坝体进行应力与变形非线性有限元计算,得到坝体在施工期与稳定渗流期的应力与变形值。计算结果表明:利用ABAQUS软件,通过二次开发可以有效的实现土石坝的应力、应变计算。The Duncan-chang model was implemented by using the user subroutine in ABAQUS which is a general purpose finite element analysis software. At the same time, heat exchange module has also been made to the analysis of seepage. Nonlinear FEM analysis was used for a earth-rockfill dam, the stresses and movements of the dam were obtained in the phases of deposition period and stability seepage period. The results of the computation showed that ： utilizing the capacities provided by ABAQUS can effectively accomplish the stress and strain analysis for Earth-rockfill Dam through redevelopment.
