Xiu Ping Wang, Ting Jiang · Applied Mechanics and Materials · 2012
It is necessary for us to monitor and forecast deformation as harm of deformation is tremendous. At the same time, deformation is seen as power system with chaos features because process of deformation is easily influenced by geology、hydrology、earthquake and activity and so on. On the base of chaos theory, forecasting model based on the maximal Lyapunov exponent is put forward in this paper, and is checked by example of engineering. Research indicate that Chaos phenomenon exist in deformation sequence for Lyapunov exponents is bigger than 0. The forecasting results show that forecasting method based on maximal Lyapunov exponent has high predictive precision, so the method is proved to be feasible and referenced.
