建筑物地基沉降曲线的分形特征分析

将分形理论应用于建筑物地基沉降曲线分析，计算两建筑物地基各测点累计沉降曲线的盒维数。分析了测点维数变化情况与最终沉降量变化情况之间的相互关系，并得到建筑物地基的沉降曲线分形特性。测点维数的大小反映了建筑物地基沉降过程复杂度，测点维数变化与沉降量变化为对应关系，反映出地基沉降的不均匀性，分形特性分析方法从一个新的角度分析建筑物地基沉降，从曲线中也挖掘更多隐含信息。

Fractal characteristics of settlement curves of building basements

The fractal theory is used to study characteristics of settlement curves of building basements. Box dimensions of accumulate settlement curves from various measured positions of two buildings are calculated; and relationships between changes of dimensions at the measured positions and changes of final settlements are analyzed. From the calculation and analysis, it is shown that the settlement curves of the building basements have fractal characteristics. The magnitude of the dimensions of the measured position reflects the complex degrees of the settlement processes of the building basements; the changes of the dimension of the measured position and the settlement have the corresponding relation. With this method, the settlements of the building basements are analyzed from a new viewpoint.
