摘　　要：根据FLAC3D软件提供的基于FISH语言的二次开发平台,结合邓肯-张非线性模型在面板坝计算中的实际需求,编制开发了邓肯-张模型计算面板堆石坝应力应变的应用程序。对某面板坝的填筑及蓄水过程进行了模拟计算,通过计算验证可知,所开发的程序应用方便,计算结果合理,丰富了FLAC3D在水利水电工程中的应用。According to the further developing platform of fish language in FLAC3D, combined with the practical demand of Duncan-Chang nonlinear constitutive model in the calculation of concrete face rock-fill dam （ CFRD）, the program of calculating the stress and strain of CFRD had been developed. At the same time, through the simulation of an actual dam＇ s filling and storage process, we can conclude that the developed program is convenient, and the calculation results are reasonable, then the application range of FLAC3D in water conservancy and hydropower engineering is expanded.
