| 摘 要： | 传统的滑坡稳定性分析大多是建立在以数学模型为基础的一种确定性分析。实际上,滑坡是一个影响因数众多,边界条件复杂的不确定复杂系统。地理元胞自动机是一种时间和空间都离散的动力系统,为之设定相应的状态、元胞空间、邻居、规则和时间,可以很好地模拟滑坡滑动面从稳定到滑移这一微观变化过程,形成GeoCA LANDSLIDE模型。以吴家湾滑坡为例,对其滑动面的演化规律进行了模拟。

| Abstract: | The traditional methods of analysis of the landslide stability are mostly quantitative and definite analysis based on mathematical model. In fact, landslide is an indefinite and complex system consisting of various factors and complicated boundary conditions. GeoCA is a dynamic system in which time and space are dispersed. When the relative state, CA-space, neighbor, rules and time are assigned for it, it can simulate the micro-change process from stability to sliding, forming the CA-LANDSLIDE model. As an example, the system is used in Wujiawan landslid, and the results is reasonable. |
