Stability Analysis Of A Loess Slope In Shanxi Province

Slope problem is always one of the main problems in geotechnical engineering.With China's reform and opening up,the domestic infrastructure construction booming,city urbanization continuously rapid development,a lot of people started the construction of the infrastructure,and the slope instability is a common geological disaster in the construction process,so the stability analysis of slope engineering has been an important research topic in the field of geotechnical engineering.Because of the complexity of the problem,in the slope engineering construction,how to correctly on the slope stability analysis and develop effective prevention and treatment scheme is still the key points and difficulties in the field of geotechnical engineering.So we should pay more attention to the stability analysis of the slope engineering problems.This paper is based on the background of Shanxi loess slope by limit equilibrium method and finite element strength reduction method,the stability of slope engineering examples are analyzed,and the slope of the slope caused by improper design of support slumping problem,do the following work:(1)This article describes the basic theory of slope stability analysis,slope stability analysis method,the main influence factors of slope stability and its control scheme;According to the location of slope engineering,the influence of loess and its characteristics on slope stability is briefly described.(2)Combined with an example of slope engineering data,the regional engineering geological conditions of the slope are analyzed,and the deformation of the slope sliding instability is statistically analyzed.(3)Using Lizheng geotechnical 6.5 software with the limit equilibrium method of slope supporting design checking analysis of the original,and at the same time,GEO5 software is used to build the numerical model of the slope engineering.Through the calculation of the numerical model,it is concluded that the original design of the project is the main cause of slope stability.(4)To redesign examples of slope engineering,and the new design scheme was re calculated by Lizheng geotechnical software 6.5 and finite element software GEO5,The results meet the safety standards of slope stability,and the conclusion is drawn that the new design method is safe and reasonable.
