The Stability Studies In High Embankment Ferret Roadbed Slope Of Mountain High-grade Highways

With the demand of human activities, the development of engineeringconstruction, and changes in environmental conditions, traffic infrastruct ure intothe stage of development by leaps and bounds, highway construction has deep intothe western mountains. Mountainous landform is complex, highway crossing, canbe seen everywhere all kinds of steep slope road section, so it is produced in theprocess of building a lot of high fill and deep excavation section. Thus, if make suremountainous area highway high fill subgrade slope digging stability, has become atimeless topic. This paper analyzes the high slope stability influence factors and theevaluation method; Exchange project for Chongqing along the Yangtze riverhighway subgrade engineering, use LiZheng software for analysis and calculation,put forward the Slope Reinforcement Scheme; Using the finite element ABAQUSsoftware of numerical simulation analysis for subgrade slope, comparison andanalyses the calculation results with the observed data in the process ofconstruction; Summarizes the main factors which influence the stability of highslope and design reference for similar projects. The main contents of this paper are:1In view of the mountainous area high fill subgrade slope dig damage form,combined with mountain special landform analysis factors affecting the stability ofsubgrade slope dig;2In this paper, the steep slope road section of high slope failure types andcauses of slope failure are expounded and analyzed, then the limit equilibriumanalysis method and the application of numerical analysis method in slope stabilityanalysis and algorithm are introduced, and analyzed the appl icability for variousalgorithms;3Chongqing communication project engineering as an example, combining theproject of steep slope road section roadbed worksite practical situation, usingLizheng software to calculate specific worksite high slope, and put forwardreasonable reinforcement measures on the basis of calculation results;4This paper uses the finite element software of ABAQUS, analysis ofchongqing along the Yangtze river highway subgrade engineering project; And thehigh fill subgrade slope digging stability are numerically simulated, combining withthe measured data were analyzed;5Through the results of numerical analysis and contrast analysis of measureddata, to make reasonable suggestions for the high fill and dig deep slope protectiondesign.
