| Abstract: | In consideration of the uncertainties of slope engineering, the material parameter and loading uncertainties of slope may be expressed by interval numbers, for which the interval Finite Element Method is used to calculate the strain and stress in a random point of a slope, and then the slope stability is estimated with the safety factor of the slope defined in accordance with the stress levels concerned. The actual engineering case shows that compared with the conventional Finite Element Method, this method given herein is convenient and simple to be used for the estimation of a slope stability with less calculation and is suitable to calculate the loading combinations therein. |
