Analysis of fuzzy reliability for retaining wall's stability |
| |
Abstract: | Retaining wall's randomness and fuzziness of stability are considered. Associating with real project condition, a probability density function for the performance function and a subjection function characterizing the stability of the retaining wall are determined. Then a practical method to calculate fuzzy failure probability and fuzzy reliability of retaining wall's stability is put forward. |
