<p>Large-scale shaking-table tests based on similarity theory were conducted to investigate the post-rainfall seismic response of a gentle near-fault slope with bedrock and overburden layer. A sequential loading path was adopted, including fault-related pre-displacement, rainfall, a 12&#xa0;h resting period, and incremental seismic excitation up to 1.2&#xa0;g. The slope exhibited staged progressive damage: deformation initiated in the rear mass behind the fault zone and generated a forward thrust on the front mass; with increasing shaking intensity, transverse shear cracking developed progressively in the front-slope zone; at the highest intensity, near-surface cracks showed a tendency toward connection and the initiation of a potential sliding weak zone, while no global sliding failure was observed. Acceleration responses displayed pronounced elevation-related and near-surface amplification, with more evident elevation amplification in the overburden than in the bedrock. Dynamic excess pore water pressure increments generally increased with shaking intensity and showed clear sensor-to-sensor differences, with systematically larger responses near the fault-zone vicinity; local reductions under the strongest shaking were consistent with shallow cracking and the development of additional drainage pathways. Hilbert–Huang indices derived from acceleration records further revealed intensity-dependent spectral changes, including a dominant-frequency downshift and non-uniform growth of marginal-spectrum peaks, consistent with the observed damage evolution.</p>
