Stability Analysis Of The Rock Slope Considering Joint Effect

With the rapid development of mining,transportation,water conservancy and construction industry,the number of open pit slope,waste rock and tailings dams and road cutting slope in rock slope engineering increased dramatically,slope instability,collapse and other disasters have occurred,the slope stability problem has attracted more and more attention and concern.Therefore,it is of great theoretical and practical significance to study the slope stability analysis and engineering measures.Based on the rock slope as an example,firstly,according to the actual situation,analyzes various influence factors of slope stability and engineering may exist in a variety of situations,find out the most unfavorable conditions,using stereographic projection method,Bisop method and Mogenstern-Price method for considering and not considering the influence of rock slope stability are analyzed separately.Calculation shows that these methods are effective discriminant analysis of jointed rock slope stability,the sensitivity can reflect the effect of rock mass structure on the stability of rock slope,verify the adverse effects of joints on the slope stability,Mogenstern-Price method can also consider a combination of sliding surface;in the above Analysis on the basis of calculation,put forward different schemes of engineering treatment and protective measures of unstable slope treatment,used for engineering design and construction.The research results of this paper can be used as a reference for similar projects.
