文章概述了枣林滑坡的工程地质情况;该边坡2001～2002年累计滑移达到10m,严重威胁附近居民以及交通安全。根据边坡工程的观测位移时间序列,基于相空间重构,给出了最大Lyapunov特征指数的计算步骤;以及给出了边坡位移时序的线性和非线性两种混沌预报模式。利用上述混沌分析方法,对枣林边坡的位移观测序列进行了分析计算,获得其最大Lyapunov特征指数为0.14;并对位移序列进行了预测;与观测位移相比较,位移预测结果比较理想。
The article summarizes the engineering geology of the Zao-Lin landslide. The cumulative slip of the slope from 2001 to 2002 reached 10m, which threatens the residents nearby and traffic safety seriously. According to the time series of observation displacement of slope engineering, the calculation steps of maximum Lyapunov characteristic index are given based on phase space reconstruction. Two kinds of linear and non-linear prediction models of slope displacement are given. The chaos analysis method is used to analyze and calculate the displacement observation sequence of the jujube slope. The largest Lyapunov characteristic index is 0.14 and the displacement sequence is predicted. Compared with the observation displacement, the displacement prediction result is ideal.
