| 摘 要： | 基于楚勐公路K64+200～K64+228路基滑坡位移观测资料,运用分形几何中的时间序列分析方法对滑坡位移变化规律进行深入研究,发现滑坡位移的赫斯特指数H与时间相关函数C(t)随着滑坡失稳程度的加剧呈现明显的下降趋势.研究表明:①2010年1月至7月,ZK2、ZK10和 ZK11的月均位移处于递增状态,位移的H与C(t...

| Abstract: | Based on the monitoring data of displacement which resulted from the subgrade lanslide of Chu-Meng Road from K64+200 to K64+228,this paper studied the change of displacement in the process of deformation by the time series analysis method on the basis of the fractal theory.It is found that the Hurst and C(t) index of the displacement shows a distinct trend of declining along with the gradual failure of landslide.It is indicated that the displacement has a synchronous dynamic process with the state of stabil... |
