With the rapid development of the national economy,the state has increased infrastructure development efforts,especially since the western development, energy,airports,highways,railways and other key projects launched in the west of the succession,and many western mountains,terrain,geological conditions complex, because of slope instability caused by the accident at the engineering often heard,the problem of slope stability has been an important aspect of engineering,this article is carried out around this topic.City of Sinopec Group supplies gas reserves of the Center for East Sichuan Dazhou send command base supporting the project,the field is located outside of the West City District,the project site east-west width of 277~401m,north and south about 740m,covers an area of about 0.23km~2.Due to the topography of site geological conditions of factors.will be formed to the east platform at 20-40m high.ranging from filling slope,fill slope height generally 20-35m,more than the local 40m,for the ultra-high fill slope its security level set.The stability of the side slop filled not only influences the design constructionoperation,construction,function and investment of project,but also restricts thefeasibility of the project,which is the key factor of the successful construction of Center for material reserves.According to the geology data and environment engineering geology estimates,which are made by the antecedents' researches,we studies on the stability oCenter for material reserves high embankment foundation with the methods of geologyanalysis,quantitative analysis,numerical simulation analysis.we studies on the engineering geology conditions of the embankment foundation.We make the geology analysis estimate on the stability of the high embankment by studied on the type of the embankment' slope,structure and the spreading features of the rock-soil mass,and so on.Find out the most dangerous slip surface by applying limitingequilibrium principle to type slope under the different conditions,and adopting many methods to count.With 2 -Dimensional Finite Element Method analysis,simulate the type section's strain stress characters.Apply the actual strain stress to count the Safe coefficient of the slope' Stability factor for the purpose of founding out the most dangerous slope.Then according to the outcome of limiting equilibrium method comprehensively analyze on the stability of the high embankment in LiupanshuiAirport.With the 2 -Dimensional Finite Element Method (F.E.M),simulate the type section' deformation,and analyze the destroy feature of the type section.According to the outcomes of the methods adopted in the research,we estimate the stability of the embankment in Sinopec Center for material reserves comprehensively,and give theconclusions.Depending on the outcomes and conclusions,we give some suggestion of the settle measure.Reliability analysis can be combined to further determine the slope to determine the impact of state and a major factor in slope stability.Filling body for the remainder of the characteristics of down force,strengthening the program in its selection on the basis of the anti-slide pile and to choose the combination of drainage measures composite reinforcement measures,and subject to anti-slide pile loads,internal forces,stability and reinforcement,such as aspects of the design and details of the parameters,the results meet the specification,design and reasonable;the end of the filling body in the process of strengthening the construction of the relevant matters should be noted.
