Study Of Mechanism And Treatment Of ZhuQuedong Landslide In The Western Hunan

The red bed is a clastic sedimentary rock mainly deposit by red ontinental Sedimentation siltstone and the rock arenaceous property is mainly composed by sandstone, mudstone, shale. Due to its formation condition, Red beds with special engineering property is typical very slip stratum, the stability of slope question is extremely prominent, there is many landslide happened frequently at rainy season.This thesis take the Zhuquedong landslide this typical red bed landslide as the object of study. The thesis entirely analyses stratum and lithology, geological structure, Rock mass structure, physiognomy and topography and the factor of influence from background of Zhuquedong landslide. The on-site investigation of the landslide region is carried on, and according to the time and deformation and failure mechanism,showed that there were three sections in this landslide region : theâ… section(upstream side intense glide area), theâ…¡section(slips the curving area)and theâ…¢section(upside two glide area).The characters of each section are written in detail. Used the energy method and the strut bracing theory has conducted the system research to the red bed slope slips curving destruction mechanism, and has given the stable determination formula. Using the natural historical analytic method, the landslide displacement monitors the analysis separately to carry on the qualitative analysis to the landslide stability. At the same time, the selection principle of the red beds area shearing strength parameter has given, and the limiting equilibrium method are used to analyse the landslide stability. Finally, proposed to this landslide the reasonable government measure, and the monitor plan.The study results contained in this paper are, to a certain degree, of academic signiticance and practical value, can be useful as a kind of reference for similar researchtopics. And will also have the important guiding sense to the next project practice.
