Stratified Structure of Granite Residual-colluvial Soil and Failure Modes of Shallow Landslides in the Qinling Mountains, China

This dataset constitutes a comprehensive, multi-scale, and multi-parameter collection designed to holistically characterize the properties of each horizon within the granite residual-colluvial soil. All data were obtained from excavated representative natural slopes on the northern piedmont of the Qinling Mountains, ensuring strict correspondence with in-situ stratigraphy. The database systematically archives multi-dimensional experimental data from the A, B, and C horizons, encompassing field investigations, material composition, pore structure parameters, hydraulic properties, and strength parameters.
