The Stability Analysis And Numerical Simulation Of Road Cut Slope In Theanhui Province

With the rapid development of the ecomomy,we have the new requirements forthe range of the road.Highway has started in the western regions and remote areas tobuild.This gives highway cut slope stability puts forward higher technicalrequirements,so the research for highway cut slope stability has importantsignificance.This paper rely on the XiangYang Village Xuan cheng City Anhui Provincehighway cut slope as the engineering background. This paper has a comprehensiveresearch combined theory analysis and numerical simulation. This paper obtained thefollowing main achievements:(1)Fistly improving Transfer Coefficient method which is one of the slopestability coefficient calculation method to get the new computational formula ofTransfer Coefficient method.As the same time getting the improved formulaconsidering the water seepage influence.(2)Secondly Through the unmerical simulation of the slope stability influencefactors,getting that in all of the factors,angle of internal friction、cohesive force andtensile strength play a positive role on the slope stability,and gradient、density、waterline play a negative role on the slope stablility,angle of internal friction has sensitivitymaximum for slope stability.(3)To establish the cut slope numerical analysis model of the practicalengineering.researching the stress、displacement、plastic zone size of the slope afterexcavation get that the slope has poor stability after excavation and the trend of thelandslide.(4)Through the displacement and plastic zone size to analyse the supportingeffect after using prestressed anchor.The supporting effect is significant,as the sametime to optimize the prestressed anchor parameters.
