摘　　要：依据FLAC3D所提供的二次开发平台,结合软土弹粘塑性流变模型,给出了具体实施的程序框图及编写概要.通过对侧向卸荷蠕变试验的数值模拟,并与FLAC3D内置的修正剑桥模型的计算结果作比较,结果表明,弹粘塑性流变模型所得到的结果更能反映软土的蠕变规律,从而验证了二次开发的可行性.With the help of the secondary development program interface provided by FLAC^3D, numerical analysis of the elastic - viseoseplastie constructive model was implemented, the program flow diagram and summary was given. Compared with the result calculated by modified Cambridge model inhered in FLAC^3D, the result of elastic - viscose - plastic constructive model can reflect more creep law than modified Cambridge model, which verified the feasibility of the developed model.
