滑坡动力系统的混沌效应分析

Analysis of Chaotic Effect in Landslide Dynamic System

介绍了滑坡监测位移时间序列相空间重构技术,并研究了适合于计算滑坡位移时间序列Lyapunov指数的算法。通过清江库岸茅坪滑坡的实测位移数据,计算出该滑坡系统的混沌特征量Lyapunov指数λ1>0,因此表明该滑坡动力系统具有混沌效应。

In this paper the reconstruction of phase space formed by the time series of displacement obtained in landslide is introduced at first, then a kind of Lyapunov exponent algorithm for time series of displacement obtained in landslide is proposed. At last this algorithm was applied to the time series of displacement measured in Maoping landslide and the result proves that there exists chaotic effect in Maoping landslide.
