Seismic loading increases deformation in zoned earth dams, with crest displacements reaching 0.030 m and 7 cm subsidence.
Cavities lead to pore pressures exceeding 2.7 kPa, highlighting their adverse effects on dam stability during seismic events.
Experimental model testing on a shake table was supplemented by numerical simulations to validate findings.
Cavity geometry proved critical for dynamic factors of safety, which fell below 0.6 for certain configurations.
