Stability analysis of rock slopes using the interface contact model and strength reduction method

The assessment of rock slope stability is usually controlled by the presence discontinuities. block theory an established method in practical engineering to predict slopes. A maximum two discontinuity planes are considered application theory. It would lead inaccurate prediction slopes with multiple planes. novel for estimating safety margin proposed, which capable considering contribution all discontinuities problem. simulated interface contact model within theoretical framework finite difference method. factor obtained strength reduction failure criteria also discussed. proposed can simulate discontinuous a more realistic manner and thus effective practice. To demonstrate effectiveness model, several numerical examples presented, showcase its superiority predicting blocks composed Several analyzed confirm formed
