Abstract According to the nonlinear failure characteristic of rock mass，a new calculation method for critical slip field of slope is proposed based on generalized Hoek-Brown failure criterion. The Hoek-Brown failure criterion based on the geology strength index(GSI ) is one of the most useful criteria for forecasting and computing rock mass strength. Firstly，the parameters of rock mass strength are obtained by Hoek-Brown failure criterion. Secondly，the shear strength of each point on the Hoek-Brown strength envelope is transferred equivalently to the Mohr-Coulomb linear relation which is tangent to the nonlinear envelope with relevant cohesive and frictional parameters. Finally，the new iterative method is established and the critical slip field of slope by Morgenster-Price method is improved. And then，the most dangerous sliding surfaces are traced according to the principle of maximum thrusts with satisfying both force and moment equilibriums；and the corresponding safety factors are calculated quickly and exactly. This method is applied to the stability analysis of two slope examples and one case slope. The results show that this method absorbs the advantages of critical slip field and Hoek-Brown failure criterion and can consider the nonlinear failure characteristic of slope. The calculation result is more closer to the practical situation.

Key words： slope engineering slope stability critical slip fields limit equilibrium Hoek-Brown criterion Mohr-Coulomb criterion
