Influencing Parameters Sensitivity Analysis And Treatment Analysis Of A Slope In Guangxi

The problem of engineering of slopes have attracted much attention in the field of geotechnical engineering due to the influence of various complicated geological conditions,In the more than two decades of rapid development of infrastructure,engineering projects have been carried out more and more frequently,and their scale has become larger and larger.At the same time,the options for engineering sites are decreasing,and slope engineering will face more complex geological conditions to a certain extent.Therefore,when dealing with slope engineering problems,more consideration should be given to the influence of slope geological conditions on its stability and its changes.Meanwhile,due to the reduction in the choice of engineering sites,engineering design will face more complicated geological conditions to a certain extent.Therefore,when designing slopes,more consideration should be given to the influence of slope geological conditions on its stability and its changing trend.At the same time,we must pay more attention to the analysis of slope engineering stability.In addition,according to the research,the influence of different factors on the displacement and deformation of unstable slope sliding is very different,and further research should be conducted on the factors that may affect the sliding displacement of the landslide.In order to obtain the main factors affecting the sliding displacement of the slope after instability Influencing factors and secondary influencing factors,so quantitative analysis of the influence of various parameters on the sliding displacement after slope instability can help to control the landslide after instability.This article introduces in detail the site conditions,engineering geological conditions,hydrogeological conditions,meteorological conditions and on-site survey data of a slope project in Guangxi,and uses the engineering slope as a background to study the influence on the sliding displacement and stability coefficient of the engineering slope Factors and the selection of support design schemes.Therefore,multiple factors that may affect the displacement and stability of the landslide are selected,and the single-factor sensitivity analysis method is used to analyze the sensitive factors of the slope sliding displacement and stability using the finite element strength reduction method of the geotechnical software Geo5 And compare and analyze the results.The sensitivity order of the factors affecting the sliding displacement and stability coefficient of the slope is obtained,and the relationship curve between the stability coefficient and the sliding displacement within a certain range is obtained.According to the characteristics of the slope,the simplified Bishop method in the traditional limit equilibrium method has been modified to better apply the slope stability analysis.Then the Lizheng geotechnical 6.5 calculation software and Geo5 geotechnical finite element software were used to select a more typical profile and quantitatively calculate its stability.Through calculation,it is concluded that the stability of the slope is poor and does not meet the requirements of the design specifications.The original slope should be reinforced.Then,using the finite element strength reduction method and the single factor sensitivity analysis method,by comparing the supporting forms,analyzing the influence of the changes of the supporting form and the supporting structure parameters on the sensitivity of the slope stability coefficient,some supporting forms are obtained.The sensitivity curve of the influence parameters and stability coefficient of the supporting structure.Finally,according to the conditions of the site,economic,reasonable and safe support measures were selected for reinforcement treatment through comparison.After redesigning the slope of this project in Guangxi,it was calculated and verified by Lizheng Geotechnical 6.5software and Geo5 geotechnical finite element software.The stability coefficient obtained met the specification design requirements,ensuring that the slope reached a stable state.Reflect the economy,rationality and safety of the design scheme.
