Research On The Stability Of The NO.2Embankment Slope Of The Maotai Airport

The thesis deals with the embankment slope of The N0.2of The MaoTai Airport.The planning airport with a complicated engineering geological condition and manyengineering geological problems. The height of the fill is almost45m in the target area.The basement of the fill area is a slope dip place of slow dip downhill roch. Therefore, itis very necessary that the research on the stability of the side slope filled.In this thesis, first of all, in order to identify the engineering geological conditionsof the study area,wu use engineering geological mapping, geophysical exploration,field drilling, in situ testing, laboratory tests and other means. On the basis of findingout in detail the foundations of the NO.2embankment slope, potentially unstable slopesborder, by means of slopes geomorphological features, lithology combination,groundwater effects, deformation and failure signs determine that The NO.2slopewhich deformation and failure model is slipping-cracking. And qualitativeclassification and quantitative. And qualitative classification and quantitative, Undernatural conditions The slope is in a stable state, but under rainstorm or seismic the slopeis in a critical state of instability. The basis of analysis so as to provide geologicalanalysis of the stability of the slopes of the NO.2slope.The high embankment slope instability based on the geological analysis, Selectedthe two fill program. Option One: Clear the topsoil, hold intense weathering dolomiteas a supporting layer. Option Two: On the basis of clear surface soil, taking muddyintercalation and intense weathering of dolomite. During the filling, Filling bodydirectly fill in the weathering of dolomite. By choosing typical section and using thelimit equilibrium method aim at calculating the two fill scheme. With the help ofthree-dimensional numerical simulation for high fill slope deformation and stability of a more comprehensive and in-depth analysis, the study area high fill slope stability hasprovided sufficient evidence. Comprehensive numerical simulation and calculation oflimit equilibrium,Selected filling scheme option Two as a proposal.Suggestions are put forward according to the scheme2filling body processingmeasures: Strict construction control of the filling, Set the geogrid and the packway infilling body, setting slope retaining wall in the Slope toe, Set in the slope measures suchas permeable layer to do a good job handling of filling body.
