| 摘 要： | 结合对高面板堆石坝的研究，对作者所提出的非线性解耦K-G模型作了进一步的改进和完善。目前，这种模型已能适应填筑坝在施工期和蓄水期的各种应力路径；可用常规三轴试验求得具有归一性的模型参数，且工程问题的有限元求解简单、可行。本文介绍这一模型的新模式及模型参数的增量回归方法，以及应用于高面板堆石坝的三维有限元计算结果。

| Abstract: | The nonlinear uncoupled K-G model proposed by the author in 1996 is further improved to accommodate the calculation of high CFRD. In this case, the stress path is very complicated since the filling process of the dam is divided into several stages during construction. The basic formula of the model and the incremental regression method for obtaining the parameters are introduced. The calculation result of Shuibuya CFRD is given as an example of the application of the proposed model. |
