混沌确定性检验原理及其在变形分析中的应用

The theory of chaotic determinism testing and its application in deformation analysis

从看似杂乱无章而毫无规律可言的观测序列中发现系统内部的一些重要信息,对变形监测的数据处理有着重要意义。本文讨论了应用混沌递归图法检验观测序列是否具备确定性的原理、算法和过程。结合长江三峡库区某滑坡的监测数据分析了该滑坡的确定性特性,并由确定性检验结果对该滑坡的稳定性进行了初步评价。

Searching the useful system information from the seemingly chaotic and undisciplined observation is one of the most important methods of deformation date processing. The theory, the algorithm and the procedure of chaotic determinism testing of observation time series based on chaotic reeursive map were discussed in this paper. With the monitoring data of Baishui River landslide in Three Gorges reservoir area, the nonlinear and determinism characteristics were analyzed. Preliminary evaluation on the stability of the landslide from the test result was conducted.
