摘要: 基于大陆地震活动的特点和已建立的由弹簧- 滑块- 阻尼器组成的平面网络非线性动力学模型研究结果,根据细胞自动机的原理,提出了对这类模型的一种简化模型— — 细胞自动机模型。其演化规则是根据大陆地震活动特点和从上述非线性模型中总结出来的,介质参数采用分维分布设定。将新建的模型应用于30× 40单元组成的较大系统中,探讨了该模型显示的一些地震活动特点。

Abstract: A simplified dynamic model——cell automat model is proposed according to the principle of cell automat based on the characteristics of continental seismicity and the research results of the non-linear dynamic model which is constituted by a plane network system built by spring—slider—damper. Its evolutional rules are summed up according to the characteristics of continental seismicity and the above no nlinear model. The medium parameters are given by using fractal distribution. A new lybuilt model with alarger system constituted by 30× 40 cells i s used in the paper, and some seismicity characteristics shown in the model are discussed.

Key words: Cell automat model, Stress distribution, Fractal distribution, Earthquake cluster activity
