摘要
为更好地描述真实的地下介质特点,提出了一种局部随机位置或固定位置任意形状截取法并结合多尺度建模技术来共同构造随机介质模型的新方法。从现有的随机建模理论出发,在有效的建模区域内产生或者给定局部扰动位置,以此作为局部扰动分布区的中心点,引入局部扰动半径R和局部随机或给定扰动角度θ两个模型特征量,采用局部位置任意形状截取法并充填各种随机介质,从而构造各种不同的随机介质模型。给出了局部位置任意形状截取法的基本步骤和应用实例。
In order to simulate the real medium underground more correctly, this paper puts forward a new method of local random position or given position arbitrary shape intercepting combined with multi-scale random modeling technology. From the existing theory of the random modeling, the local disturbing position is given in the effective modeling area and this position is taken as the central point of each disturbing distribution. Two model characteristic quantities, namely the local disturbing radius R and the local random or given disturbing angle , are introduced, and all sorts of different random medium models are simulated by the method of local position arbitrary shape intercepting and filled with each random medium. This paper presents basic steps and application examples of the model.
