Abstract An analytical method is presented using the blind data theory considering a variety of uncertainties of parameters of rock and soil in slope engineering. The blind data safety factor of the slope with the reliability of minimum safety requirement is firstly presented as the comprehensive index to evaluate slope stability. Firstly，the limit state equation of the slope is solved by using the response surface method and the strength reduction method of FEM，the blind data model of safety factor is established based on the blind data theory，and the blind data solution is derived. Secondly，the expressions of blind data safety factor of the slope and reliability of minimum safety requirement are established. The blind data safety factor of the slope and reliability of minimum safety requirement obtained were smaller in comparison with ones from the traditional methods. Thus，it will be safer for engineering assessment.

Key words： slope engineering reliability blind data response surface method strength reduction method
