分形学在大坝监测数据处理中的应用

Application of fractal theory to analysis of the observed data of dams

直接应用分形分布模型难以分析某些大坝的监测数据,这是因为这些数据往往存在着一定的非线性关系。在这种情况下,文章借助于变维分形的概念,将数据进行一系列变换,使变换后的数据能近似地与一条直线相吻合,从而可以用一般的常维分形来处理;工程实际说明,用变维分形技术来处理大坝数据具有一定的实用价值。

It is difficult to analyze the observed data of some dam by directly using the fractals distribution model because these data often have nonlinear relation. With the aid of the conception of variable dimension fractals, the data can go through a series of transforms, which makes the transformed data agree well with a straight i^ine, thus the transformed data can be handled by using the general fractals method. An application example is presented, which proves that it is practical to analyze the observed data of a dam by using variable dimension fractals .
