摘　　要：引入面向对象的程序设计方法，利用随机有限元法的通用性及其灵活性，结合C＋＋语言的封装性、继承性和多态性等优点，采用Visual C＋＋ 6．0设计了泰勒展开随机有限元和基于随机场局部平均理论的摄动随机有限元法相关的类及其方法，并编制了随机有限元计算程序。这种程序不仅可以用于随机结构的分析，还可以用于进行确定性问题的有限元计算，而且程序结构清晰、代码重利用率高、更易于维护和扩充。： On the combination of commonality and adaptiability of stochastic finite element method（SFEM）with the features of C＋＋ such as encapsulation and inheritance as well as polymorphism，the object－oriented programming（OOP）is used to design the typical classes and the methods on SFEM base on Talyor series and SFEM based on perturbation theory and local average of random field in Visual C＋＋6．0．And the corresponding SFEM software is programmed．This kind of program is easier to analyze both stochastic structures and determinate FEM problems．Compared with traditional SFEM programs，this program is more reusable and more structured as well as more easily to be maintained and expanded．
