| Abstract: | An analysis of slope stability using two kinds of intelligent response surface methods is presented in this paper based on the relative sensitivity analysis of the structural reliability parameters.Specific ideas are as follows: to access the main influencing parameters of the slope reliability based on the relative sensitivity analysis of the random variable distribution parameters with reliability index;to replace the implicit limit state function of response and basic variables by the network models of t... |
