| 摘 要： | 针对泥质页岩多孔、遇水易分解的岩性,基于剑桥粘土模型,建立了一个涉及多孔岩土材料的弹塑性本构模型,并数值模拟了某软弱泥质页岩隧道的力学行为.从混合理论出发,把泥质页岩体看成一个由固体(土)-流体(水)-气体(气)组成的三相混合体,引入有效应力的概念,建立了一个适用于工程实践的本构模型,该本构准则反映了有效应力与固相矩阵...

| Abstract: | On the basis of Cam-clay Model,a proposal constitutive model on porous elaso-plastic geo-material was derived for the argillaceous shale,which was porous and easy to decompose with water,and then the mechanical behavior in an argillaceous shale tunnel was simulated.According to the mix theory,the argillaceous shale was analyzed as a three-phase mixture coupling with solid-liquid-air,and the effective stress was introduced to set up a proposal constitutive model.The constitutive laws relate: the evolution of... |
