Many factors influence the shear resistance of rock joints.
Among them, the above overburden load is the most important factor.
The uneven thickness of the overburden causes the joints to be subjected to the nonuniform distribution load.
While the peak shear strength shows nonlinear relationship with normal stress, linear superposition cannot be used to calculate the overall shear resistance of joint under nonuniform normal stress distribution.
In this paper, the nonlinear shear strength model, JRC-JCS model, is applied to study the overall shear resistance of the joint under four nonuniform distribution patterns of normal stress.
The results show that when the normal stress is distributed in a nonuniform way, the shear resistance provided by rock joint as a whole decreases with the increase of the normal stress distribution interval.
Given the nonuniform distribution of normal stress along the joint, the shear resistance obtained by the Mohr-Coulomb linear model is overestimated.
In order to give full play to the overall shear performance of the joint, the shear strength at different positions on the joint should be as close as possible.
Then, the shear strength of joint parts can enter peak state condition simultaneously, at which time the shear strength is fully exerted.
