Abstract

In recent years, torrential rains have occurred frequently owing to abnormal weather and the rainy season, thereby resulting in numerous slope failures. When rainfall occurs, the infiltration of rainwater and the inflow of groundwater from upstream may reduce the shear resistance in the slope, and the infiltration water pressure may result in slope failure. In addition, the change in groundwater on natural slopes is significant, and the amount of groundwater inflow from upstream increases, which may result in slope failure. The purpose of this study is to reproduce and stabilize the increase in groundwater level on the target slope via numerical analysis and to consider the effect of hydraulic conductivity on groundwater level increase and the safety factor. In addition, we propose a method for observing the penetration of groundwater due to rainfall and the change in groundwater depth using a wireless sensor network for sedimentation grounds. Furthermore, we clarify the progress of slope deformation and the correlations between rainfall, groundwater depth fluctuation, and slope deformation.
