The Application Of Finite Element Analysis Method In The Landslide Treatment Design

With the rapid development of China's economy and the impact of natural factors,landslide disaster showed a trend of increase year by year,of which most serious in the western region,in the western region in yunnan,guizhou,sichuan three provinces of landslide disaster is the most typical.With speed up mountain area highway construction,a large number of construction or to be built by the highway will all through the bad geological condition area,system research of highway landslide development pattern and management measures,is very important for highway construction.In this paper,the current domestic and foreign large-scale landslide disaster has carried on the simple summary,and simply introduces the significance of landslide in highway construction;Summarizes the status and evolution mechanism of landslide formation at home and abroad and the research status of landslide control measures at home and abroad;Summarizes the scope and the application of finite element analysis method in the landslide control.Finite element analysis method was introduced in detail in the landslide stability analysis and the application of retaining structure internal force calculation,and by comparing the difference between the traditional method and finite element method to calculate theory,summarizes the shortcomings of traditional methods and the advantages of the finite element method(fem).This paper takes kunming to Jiaozi snow mountain highway K9 landslide control project as the background,According to the geological environment,landslide characteristics of practical engineering,By finite element method and the traditional limit equilibrium method for stability analysis of landslide,draw a K9 landslide in thecondition of abnormal conditions in a state of flux.Then studied the landslide treatment measures,slide-resistant pile measures are put forward,and expand the slide-resistant pile design research,through the finite element method and traditional method,analyses the internal force of slide-resistant pile calculated respectively,calculate the slide-resistant pile bending moment,shear force of pile,pile lateral earth pressure and displacement of pile body,provides theoretical basis for slide-resistant pile design.Finally use the finite element analysis software,Analysis on the stability of landslide,confirmed the effectiveness of the proposed control measures.In the process of landslide stability analysis and slide-resistant pile internal force calculation,using the finite element method and the traditional method,through calculating,validate the correctness of the finite element method to calculate the results and finite element method(fem)is a traditional method of ease of use in the design work.
