    Abstract
  • With MATLAB optimization toolbox, the parameter variability of soil was considered, the reliability index and corresponding safety factor of slope were computed by using response surface method(RSM)with quadratic sequence, and the safety factor was reduced by using the corresponding failure probability of the reliability index. A combined evaluation method, named reliability index and reduction safety factor evaluation method, was set up, the stability of slope was evaluated, and the calculation result and the failure surfaces obtained by the method were compared with the results obtained by traditional certification method and median reduction method of safety factor in dual index method. Comparison result indicates that slope may be unreliable with a safety factor(greater than 1)calculated by using traditional method when the parameter variability of soil is larger. In the present method, the reliable part of the safety factor is gotten by the reducing process, simultaneity, the unreliable part resulted from ignoring the uncertainty is deleted, so it can give a reasonable evaluation for practical slope.
