摘要
基于弹—粘塑性有限元方法,探讨了通过反分析来确定P.Perzyna粘塑性本构模型中反映岩体粘塑性变形的流动系数和屈服函数的函数的方法,并用实测数据检验了这一反分析方法的可行性。
Based on the finite element method of elastic-viscoplasticity, a back analysis method for the determination of the viscoplastic parameters of P. Perzyna's constitutive equation is proposed. The feasibility of the back analysis method is verified through in-situ measurement data.
