摘　　要：结构性是黄土的典型特性。为了模拟黄土的结构性特性,将笔者所建立的黄土湿载结构性本构模型应用于工程实践,基于通用商业软件FLAC^(3D)平台,运用C^(++)语言程序,在FLAC^(3D)中通过UDM进行了二次开发;并将黄土湿载结构性本构模型数值化,验证了数值开发程序的稳定性。结果证明,所建立的黄土湿载结构性本构模型参数稳定,通过UDM进行二次开发嵌入FLAC^(3D)可行。Constitutive property is the typical characteristics of loess.In order to simulate the structural characteristics of loess and apply the loess structural constitutive model under moisture and loading to engineering practice conveniently,the loess structural constitutive model which was proposed in this paper which was development based on the FLAC^3D platform of common commercial software by using the C^＋＋ language program.The stability of the model was verified.The results show that the parameters of constitutive model are stable under moisture and loading and it is feasible to embed FLAC^3D by UDM.
