Abstract Stability analysis is made on the jointed rock slope by nonlinear FEM strength reduction method. With the c-j reduction，the nonlinear FEM model of jointed rock slope reaches instability and the numerical non-convergence occurs simultaneously. The safety factor is then obtained by c-j reduction algorithm. At the same time the critical failure surface and overall failure progress are found automatically. This presents a new approach for jointed rock slope stability analysis as the traditional limit equilibrium method can't get the safety factor and failure surface of jointed rock slope. Through a series of case studies，the applicability of the proposed method is clearly exhibited.
