Under climate change the landslide disaster induced by rainfall has become frequent than before The empirical warning method based on the statistics results of history failure case the short-duration intense rainfall cause inaccuracy in the empirical method In this research a time-dependent warning framework for the shallow and deep soil slope failure proposed Based on the coupled hydromechanical analysis the time-dependent infiltration analysis and slope stability analysis performed Under the consideration of the failure mechanism of soil slope the volumetric water content or the groundwater elevation is being as a time-dependent index for monitoring the failure behavior of a shallow or deep slope site Moreover the developed IoT sensing module can provide the real-time and continuous hydromechanical response in filed under the rainfall event From above a customized time-dependent warning system for rainfall-induced soil slope failure is constructed The research results can provide judgment based on field evacuation for local administration
