The traditional safety factor method cannot consider the uncertainty in the slope system, and the reliability theory based on probability and statistics can more objectively evaluate the degree of influence on the slope, which has become a trend of slope stability evaluation. In this paper, the spatial variability of soil strength parameters cohesion c, internal friction angle φ is considered to build a stochastic variable model, the Monte Carlo method is adopted to study the effect of reliability index β for two parameters. The results shows...
