摘　　要：流变是岩土材料的一种重要的力学性质,合理地分析和模拟材料的流变对结构施工期和运行期的变形和应力控制十分重要.由于流变计算较为复杂,目前常需借助一些相关的计算软件来实现.本文首先介绍了流变分析的相关理论,然后以有限元分析的商业软件MSC.Marc为基础,进行二次开发,编制相关的计算子程序,来实现流变计算.以某抽水蓄能电站的堆石坝为算例,根据计算的结果对开发的程序进行了验证,表明开发的程序可以应用于实际工程.Rheology is one of the most important mechanical properties of rock and soil materials. It is very important to analyze and simulate the deformation of material reasonably for deformation and stress control during construction and operation. Due to the complexity of theological calculation, it is often necessary to use some related software to realize. Firstly, this paper introduces the theory of theological analysis; and then the paper prepares relevant calculation subroutine to achieve the theological calculation based on secondary devel opment of MSC. Marc. Taking a rockfill dam of a certain pumped storage power station for example, the de veloped program is validated according to the calculation results, so as to show that the developed program can be applied to practical engineering.
