Abstract: The geological environment of China's southeast coast is complex and fragile,with frequent landslides triggered by typhoons and rainstorms. The key factor that leads to the deformation of the slope body,then landslide and mudslide is the rainwater infiltration into the soil. This paper studies the landslide in Yandou Village. It is located in the east of Fujian Province. The study uses a self-developed artificial rainfall soil columns infiltration experiment device. It considers different rainfall,rainfall duration,rainfall interval time,and other working conditions. It conducts different cumulative cyclic rainfall experiments on the slope residual soil of landslides at different rainfall intensities(20 and 60 mm·h^-1). The experiments give the rainfall infiltration data,including changes in water content,resistivity,and matric suction of soil under drying and wetting circles. The analysis of the test results show the following findings. (1) Under cumulative rainfall circumstances,the peak water content of the upper soil slowly decreases with the increase of wet and dry cycles times,while the deeper soil gradually accumulates water content and the peak water content slowly increases. (2) The soil columns feature heterogeneity. Different depths of soil show various resistivity. There is a highly correlation between the resistivity response time and the water content response time. The resistivity changes almost simultaneously when the water content changes,but these changing indicators are on the contrary. (3) The matric suction represents a very limited recovery during the rain-stopping phase of the cumulative rainfall. From the second rainfall,due to the water of the last rainfall still remaining in the soil,the matric suction drops to 0 kPa after cumulative rainfall. (4) The errors can be smaller using the expansion Archie model modified by Keller to conduct resistivity and water content fitting in the research area. This paper combined the expansion Archie model,the Green-Ampt model,and the Philip infiltration model to obtain the Green-Ampt and Philip infiltration model based on resistivity. This provides a new measurement perspective for soil infiltration with practical value. The results of this study contribute to exploring further the resistivity evolution of slope residual soils under the action of typhoons and rainstorms in the research area. In addition,the achievements reveal rainfall infiltration mechanisms of slope residual soil under cumulative rainfall circumstances that are of important theoretical and practical significance to analyze the stability of typhoon and rainstorm type landslides and to monitor and early warning activities.
