摘要
Abstract
To study landslide deformation trend and time effect, first, the cubic spline interpolation was used to preprocess the monitoring data. Then, R/S method was adopted to analyze the measured data at the monitoring points and the time effect of landslide deformation. The results indicate that the Hurst index of the two sequences at each monitoring point is greater than 0. 5, which shows a successive growth trend, but the deformation-time sequence is more persistent than the rate-time sequence. Moreover, the analysis on time effect of the landslide deformation shows that the main deformation route will change with the suc-cessive deformation in later period, which makes deformation trends of the rest monitoring points change as well. The study on the trends and time effect of the landslide deformation can guide the engineering treatment of rockslides in future.关键词
