A Method to Predict the Time of Slope Failure Caused by Rainfall Using the Inverse Number of Velocity of Surface Displacement

Abstract

In order to study the process of slope failure caused by heavy rainfall, some large scale slope models of loamy and sandy materials were constructed. Artificial rainfall was applied to these models until a large scale failure occurred. Surface displacement were monitored by extensometers set on the models from the beginning of experiment to the final failure. Through analysis of the data, a rule on slope movement in the process of failure was found.
