摘要
The present study considers the damage mechanisms and the rainfall infiltration process responsible for landslide phenomena which originate from accumulation slopes.Accordingly,a physical test model is developed for different slopes and different rainfall conditions.Moreover,a three-dimensional laser scanner and a camera are used to monitor the slope erosion and the landslide dynamic evolution.Using this approach,the time variation curves of volumetric water content,pore water pressure,soil pressure,slope deformation,and damage are determined.The results show that under similar conditions,similar trends of the pore water pressure are achieved for different slopes and rainfall intensities.
