Abstract：Effective landslide forecast can improve the early warning system of landslides and mitigate the landslide disasters.The phenomena of landslides in flume experiments and the stability of unsaturated soil slopes were analyzed.The evident difference of failure time between experimental slopes and numerical analysis was shown.Consequently,it was hard to use the landslide forecast of numerical analysis owing to the uncertainty of unsaturated soil parameters and matric suction distribution.Moreover,the reasonable shear strength criteria of unsaturated soil also had effect on the inaccuracy of forecast.These results could be used to provide the deliberate aspect to develop the theoretical basis of landslide disaster prevention.
