摘　　要：针对土石坝施工运输系统存在的模糊性以及传统的仿真方法难以将时间、空间和系统行为有机地结合起来的缺陷 ,提出了基于元胞自动机模型的施工运输系统的模糊仿真方法 .用离散型模糊分布取代传统的概率分布以适应实际数据较少或系统参数概率分布难以确定的场合 ,并充分利用现场知识和经验 ,用元胞自动机模型描述土石坝施工运输系统 ,将运输系统的时间、空间和系统行为有机地联系在一起 ,形象、直观、精确地完成运输系统的仿真 .In consideration of the fuzziness in the transportation system for earth rockfill dam construction and the difficulties in the combination of time, space, and systematic actions in conventional simulation methods, a cellular automation based fuzzy simulation method is proposed for the transportation system. By replacement of the conventional probability distribution with the discrete fuzzy distribution, the method is suitable to the cases in which the number of data is small, or it is difficult to determine the probability distribution of the system. The method, by full use of the field knowledge and experience, uses the model of cellular automation to describe the transportation system during the construction of earth rockfill dams, and combines space, time, and systematic actions together, realizing the simulation of the transportation system visually and precisely.
