摘　　要：为深入研究混凝土细观结构,运用可视化软件Matlab结合蒙特卡罗方法自动生成混凝土三维球形骨料模型,并利用有限元软件对其进行网格划分和网格检查.模拟结果表明:利用Matlab建立的混凝土骨料模型,实现了骨料生成的随机性;生成的骨料具有很好的连续性.该方法通俗易懂,模型直观且精确性高,有利于对混凝土的宏观、细观力学性质做进一步的数值研究.For the further study of the meso-strueture of concrete, Matlab and Monte Carlo method were combined to automatically generate the concrete three-dimensional spherical aggregate model and use the finite element analysis software for grid division and check of the model. The simulation results show that the established model achieves the randomness of aggregate generation and the generated aggregate is con- tinuous. The method is simple and easy to use, and the model is visual, highly accurate, and conducive to further research of the macro and micro mechanical properties of concrete.
