Prediction of slope displacement by using Lyapunov exponent improved technique

An improved Lyapunov exponent algorithm for small data sets is introduced. This method is not only reliable to small data sets, but also of less computation amount and easy to handle. On the basis of the characteristic analysis of slope displacement time series, the largest Lyapunov exponent is obtained. Moreover, the slope displacement is predicted by using one-dimension mode. The improved method is more reliable than existing ones. The slope displacement prediction is made for the Three Gorges Project shiplift slope and Xintan slope slide, and the results are satisfied.
