摘要
针对水闸监测数据信息量大、错综复杂、彼此存在相关性的特点,将分形理论应用于水闸安全监测数据分析研究中,对闸室底板渗压时间曲线的盒维数进行分析。结果表明,测点的分形盒维数可反映与渗流相关的地基均匀程度、复杂程度、相邻测点的自相似性,且测点的渗压值曲线变化复杂程度与该点的盒维数大小成正比。采用分型理论对水闸监测数据分析可获得整个闸室底板渗压值全场变化规律,为水闸安全提供保证。
In view of large amount of information,complexity and relativity in gate monitoring data,the fractal theory is applied to analyze gate safety monitoring data.And then the box dimension of seepage pressure-time curve of sluice floor is analyzed.The results show that the fractal box dimension of measure points can reflect the uniformity and complexity of the foundation associated with the seepage,and the self-similarity of adjacent measure points;the complexity of osmotic pressure curve is proportional to the box dimension of each point.Analysis of gate monitoring data with fractal theory can obtain the variation rule of osmotic pressure of the whole chamber floor,which can provide guarantee for the gate safety.
