Field Experiments of Rainfall‐Induced Weathered Granite Residual Soil Shallow Landslides

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Affected by the extreme climate in recent years, the heavy rainfall has induced a large number of shallow landslides along roads in the granite residual land area in southeast China. Currently, the hydraulic response, evolution mechanism, and failure process of unsaturated granite residual soil landslides at the field scale are not well understood.
