| 摘 要： | 从岩土材料弹塑性本构模型的通式出发，把本构模型类内识别问题转化成一个典型的参数辨识问题，并采用新近提出的对参数辨识具有良好性能的新型仿生算法--免疫进化规划进行了弹塑性模型类内识别研究，提出了一个新的模型识别进化方法。一个标准算例证明，所提方法具有良好的模型识别效果，能仅在已知量测位移的情况下，得到理想的模型形式，具有潜在的工程应用价值。

| Abstract: | From the united constitutive law of geo-material elastoplastic model, the problem of model identification among one model type is transformed to a problem of parameter identification. So, using the new bionics algorithm, immune evolutionary programming (IEP), proposed by authors recently, the elastoplastic model identification among one model type is studied; and a new model identification method is proposed. At last, this method is verified by a numerical example. The results show that this method can get the suitable geo-material model when only displacements are known. |
