含黏粒砂土的循环弹塑性本构模型及其动力数值研究
Cyclic Elastoplastic Constitutive Model of Clayey Sand and its Dynamic Numerical Analysis
摘要
Abstract
The definitions of overconsolidation state parameter R and structural property state pa-rameter R * are perfected,and a new derivation of the super/subloading yield surface model is of-fered based on these definitions.The numerical implementation based on this unified constitutive model is compiled,and the simulation is carried out.The mechanical characteristics of clay and sand and the differences between their state parameters are analyzed.The numerical implementa-tion of clayey sand is then simulated based on the theoretical analysis.To find the correspondence between the numerical parameters and the clay content,simulations of clayey sand with varying parameters are carried out.关键词
