Based on a comprehensive analysis of geotechnical parameters

the interval analysis method and non-probabilistic reliability thinking were introduced to establish non-probabilistic reliability analysis mode for rock slope stability.In addition

as for the question of the expansion of interval calculation result

the interval-truncation approach and interval optimization method were adopted to obtain non-probabilistic reliability index more accurately.Finally

the effect of the variability of rock parameters on the non-probabilistic reliability of the rock slope stability was further explored

by taking a high rock slope in Hubei as an example.
