Since the movement of landslide displacement takes on a dynamic nonlinear process, the theory and method on landslide nonlinear dynamics should be studied deeply to analyze the stability correctly and forecast the landslide effectively. Based on the landslide force transmission method, this paper got a dynamic equation from Newtonian movement law using the finite difference method, and put forward a method for landslide nonlinear dynamics modeling. Some modeling results under different loading on Ganhaizi landslide near Xiluodu hydropower station are given at the end of paper.8figs.,7refs.
