| 摘 要： | 介绍了土石坝筑坝材料本构模型参数反演计算原理，并采用基于免疫遗传算法的反演方法并结合某面板堆石坝筑坝材料大型现场压缩试验，对该面板坝筑坝材料的E—B模型参数进行反演计算，分析计算结果的合理性，说明此反演结果可以对筑坝材料的室内三轴试验结果进行修正，并为原型大坝的变形与应力分析提供更为可靠的依据。

| Abstract: | This article described inversion principle of dam material constitutive model parameters, and inversely calculated E--B model parameters of a CFRD dam material combined with the large damming material compression test and based on immune genetic algorithm inversion method. Then the paper analyzed the reasonableness of the result, indicating this result can correct damming materials laboratory triaxial test result, which provided a more reliable basis for the prototype of the dam deformation and stress analysis. |
