摘要
为研究介质非均匀性与地震活动的关系,编制开发了模型可定制的二维细胞自动机模拟软件。针对软件设计中出现的非均匀断层结构模型的建立、系统模拟数据记录结构设计以及内存管理等问题,提出了解决方案。改善了模拟系统所需的几种关键算法,使研究人员能根据需要灵活设定模型的介质参数。并利用内存管理技术,在一定程度上解决了大型模拟系统中普遍存在的硬件瓶颈问题,从而提高了细胞自动机模拟系统的适应性。
In order to study the interrelationship between the non-uniformity of earth media and the seismic activity,were developed a two-dimensional cellular automata simulation software which the model can be tailor-made.In this software,the solution methods are put forwarded on how to set up the non-uniform fault structure model of the earth,how to design the simulation data record structures,how to manage computer memory and other issues.Meanwhile,several key algorithms in this software were improved,so that the researchers can according to their own unique requirement to set up the earth model.through use of memory management technology,broke through the ubiquitous hardware bottleneck in the large-scale simulation system,thereby enhancing the cell automata simulation system flexibility.
