Shaking Table Test on Dynamic Response of Bedding Rock Slopes With Weak Structural Plane Under Earthquake

A shaking table test revealed that bedding rock slopes with weak structural planes exhibit significant seismic response variations under different earthquake conditions, particularly demonstrating 'elevation' and 'surface effects.' These effects weaken as seismic amplitude increases but become more pronounced with resonance induced by specific seismic waves, such as the EL Centro wave. The study identified a two-stage failure mechanism: initial formation of a sliding shear plane followed by overall slope instability. Conducted at a 1:10 similarity ratio, the test analyzed acceleration and displacement responses to simulate earthquakes like Wenchuan Wolong and Kobe, providing critical insights for understanding and mitigating seismic risks in fragile geological settings.
