| Abstract: | A new method based on the chaos theory is used to assess the evolution process of a slope system. The method is applied to
the Xintan landslide and the results show: (1) the slope movement is a complex process of the slope going in and out of the
stable and chaotic state; (2) the method reveals the evolution process of the slope pointing to the slope failure while the
observed movement shows a simple monotonic increase with time; (3) the method is not sufficiently mature to precisely predict
the time of failure but it has potential for improvement with further research and more field data for analysis. |
