摘要
基于塑性理论,推导出湿陷性黄土湿陷变形本构模型,给出其矩阵表达式.基于ADINA分析软件,开发湿陷性黄土湿陷变形本构模型,给出湿陷性黄土湿陷本构模型开发方法及步骤.结合工程案例进行湿陷变形计算和固结分析,并用实测结果与大型非线性有限元软件ADINA模拟值进行比较.结果说明,该湿陷本构模型用于大厚度湿陷性黄土地区的分析和湿陷变形计算是可行的.
Based on plastic theory,the constitutive model of wet-collapsible loess deformation is deduced and its matrix expression is given.This constitutive model is developed and its development method and procedure are given based on the analysis software ADINA.An engineering case is illustrated to conduct the wet-collapsible deformation calculation and consolidation analysis,and its actual measurement result is compared to the simulation value with large-scale nonlinear finite element soft ware ADINA.The result shows that it is feasible to use this constitutive model for analysis and calculation of wet-collapsible deformation in the region with large-thickness collapsible loess.
