Based on dynamic shear/true triaxial-seepage coupling tests and large-scale shaking table physical model tests, this study analyzed the damage-dilatancy response mechanism of slip zones/soft layers in structurally controlled landslides under dynamic loading-seepage coupling, clarified the true triaxial strength evolution law of rock masses in locked segments under dynamic loading-seepage coupling, and revealed the instability mode and multi-parameter evolution process of gently dipping bedding rock slopes with weak interlayers under dynamic loading-seepage coupling.
