Abstract EN
Rock slope commonly fails due to the shear failure of rock fractures.
Shear strength of rock fractures are reduced substantially once the fracture surfaces are mismatched or opened.
We propose a new criterion to predict the shear strength of rock fractures in different opening states.
The degree of interlocking representing the true asperity contact area is incorporated into the modified model of Saeb and Amadei.
The effect of fracture opening on asperity dilation and degradation is separately considered.
The transitional stress that is a critical parameter involved in the model is analytically determined based on energy consideration.
The new model is validated with experimental results from direct shear tests on synthetic fractures with regular-shaped asperities.
Good agreement between the analytical solution and the experimental data confirms the capacity of the proposed model.
Therefore, the model has great potential for assessing the stability of rock slopes where fractures are often opened due to stress relief and engineering disturbances.
