英文摘要Rainfall-induced shallow landslides (i.e., the depth of the failure surface is less than 5.0 m) have been widely investigated in the literature. However, the relationship between water infiltration and deep-seated soil landslides (e.g., > 20 m) has not been fully understood. The paper presented here aims to investigate the cumulative influence of infiltration on the stability of the slope with a thick unsaturated zone. The Yanlian landslide induced by the steam released from heating pipelines of an oil refinery is introduced. The original slope has an unsaturated zone of 45 m. Field investigations have been undertaken to obtain the geological and morphological characteristics of the landslide. Triaxial shear tests, soil-water characteristic curves, and permeability measurements were carried out to achieve the mechanical and hydraulic properties of the soils. Besides, numerical simulation was adopted to investigate the spatial and temporal variability in pore water pressure within the original slope. Variation of the slope stability associated with the cumulative infiltration was documented. The results highlight the cumulative influence of infiltration on the hydraulic condition of the slope and the associated variation of the slope stability. The hydraulic condition reaches a dynamic equilibrium state (i.e., stable groundwater table, constant water flow in the unsaturated zone, similar outflux to influx) under cumulative infiltration conditions. Disturbance of the equilibrium state (e.g., irrigation, climate change) will cause the hydraulic condition to transform into a new equilibrium state. The results presented here are helpful to understand the cumulative influence of infiltration on the deep-seated soil landslides.
