| Abstract: | A hybrid genetic algorithm with two-stage for the slope reliability is proposed in the paper.A uniform mathematical model is formed used for the study.It can be used to calculate the reliability index and to search the critical slip surface.It is also discussed that the correlativity of random parameters is how to influence on the reliability index.Some examples are given in the paper.It is found that the critical slip surfaces based on minimum safety factor are inconsistent with that based on the reliability index.The slope more complex the difference more large |
