| 摘 要： | 为了提高ABAQUS软件分析土体的准确性,对软件中运用的弹塑性本构模型Drucker-Prager和修正剑桥两种模型的特点和应用的参数进行了分析。结果表明弹塑性本构模型Drucker-Prager与修正剑桥模型的适用范围、条件以及参数的选取各不相同。Drucker-Prager适用于砂土等粒状材料,修正的剑桥模型适合于正常固结粘土和弱固结粘土。

| Abstract: | For improving the accuracy of ABAQUS software analysis of soil,we use the software in the elastic-plastic constitutive model Drucker-Prager and modified Cambridge mode,and the application of the parameters of the two models was analyzed.The results show that elastic-plastic Drucker-Prager constitutive model with the modified Cambridge model scope of conditions and the selection of parameters varied.Drucker-Prager applies to sand and other granular materials,while the modified cam-clay model is suitable for ... |
