Abstract

Buckling deformation of bedded rock slope is common in the northern region of the Hunza river along China-Pakistan International Karakoram Highway (KKH), Pakistan. In order to analyze the failure mechanism, an explicit general failure formula is established to depict the flexural buckling of plane slopes subject to seismic force based on the theory of column stability and stress equilibrium. A comparison is made between the flexural buckling subject to seismic force and the buckling without seismic force. The rock slope of K745 at KKH is analyzed to evaluate the effects of three key parameters – seismic force (horizontal acceleration), slope inclination angle and friction angle.
