摘　　要：随着油页岩水平距离的变化,传统模型模拟的油页岩热量差值变化幅度较大。针对这一问题,基于Matlab和Monte Carlo方法设计一种新的油页岩非均质热弹塑性损伤模型。在分析Matlab和Monte Carlo方法特点的基础上,确定油页岩的非均质热弹塑性损伤的演化阶段,通过油页岩体变形场控制方程和油页岩温度场热传导方程确定油页非均质参数和热损伤变量。实验结果表明,基于Matlab和Monte Carlo方法构建的损伤模型能够有效缩短油页岩水平距离的变化以及热量差值变化幅度,充分证明了应用Matlab和Monte Carlo方法的有效性。With the change of the horizontal distance of oil shale,the caloric difference value of oil shale simulated by the traditional model varies greatly.In view of this,a new oil shale heterogeneous thermal elastoplastic damage model based on Matlab and Monte Carlo methods is designed.On the basis of the analysis of the characteristics of Matlab and Monte Carlo methods,the evolution stage of heterogeneous thermal elastoplastic damage of oil shale is determined,and the heterogeneous parameters and thermal damage variables of oil shale are determined by the governing equation of oil shale deformation field and the thermal conduction equation of oil shale temperature field.The experimental results show that the damage model based on Matlab and Monte Carlo methods can effectively shorten the change of oil shale horizontal distance and the change range of thermal difference value,which fully prove the effectiveness of Matlab and Monte Carlo methods.
