Deterministic and Probabilistic Analysis of Slopes Considering Variability of Geotechnical Parameters
摘要
Abstract
The physico-mechanical parameters of geotechnical bodies generally exhibit some spatial variability,which has an impact on the ac-curate calculation of the factor of safety of slopes.And usually the parameters of deterministic geotechnical bodies are used in the traditional slope design.To address this,an effective framework for evaluating the stability assessment of overburden rocky slopes is proposed in this pa-per.The overburden rocky slope model was established by numerical methods for deterministic analysis;based on the limit equilibrium meth-od,the damage probability of the overburden rocky slope was calculated by the Latin Hypercube Sampling(LHS)method.The results show that the variability of the internal friction angle has a greater influence on the failure probability compared with the cohesion;the correlation co-efficient between the cohesion and the internal friction angle has a significant influence on the slope stability,and the strong correlation of the rock parameters is beneficial to the stability of the slopes,and ignoring the correlation coefficient may overestimate the damage probability of the slopes.关键词
