Study on the Identification of Overlay Rheologicai Model Based on Complez Optimization

摘要：

With the merits of overlay model easy to be realized by programming,the viscosity,elasticityand plasticity of soft soil are expressed by overlay model,furthermore,the program OMFEM(OverlayModel with Finite Element Method)computing the rheological behavior of soft soil based on overlaymodel is developed. Then,the global search of rheoiogical parameters is realized by complexoptimization,with the integration of computing program OMFEM and complex optimization,theidentification program COIOM(Complex Optimization Identification of Overlay Model)of soft soilrheological model is developed based on complex optimization and overlay model．and theidentification of model parameters and rheological model is realized. In the end,the example shows theavailability of the identification of soft soil rheological model based on complex optimization andoverlay model．
