| This research chooses Chongqing town Yunyang County of Sheng Yuancun landslide as anexample. The first collection of previous studies, followed by the field survey to understand thebasic geology, survey, mechanical test. Finally to landslide stability as the core, using theprototype investigation and indoor analysis, combining the macro analysis and micro analysis,combining the analysis of engineering geology and rock mechanics, combined with field andlaboratory test combination, mechanism analysis and simulation study of combination, hierarchyanalysis and evaluation system, combining the geometry analysis and mechanics analysis ofcombined the train of thought of the landslide, formation mechanism and stability of the systemanalysis and research.The Wa Guang Yao landslide main sliding direction for310°(The Changjiang River andYangJaGou junction point), long approximately480m, width of about100m, area of4.8x104m2, the volume of about29x104m3. Average thickness about6m. Slippery body mainly by theartificial fill silty clay soil, composed, slippery body thickness0.00~11.7m, vary considerably.Slide soil for light yellow plastic shape silty clay clip gravel, gravel composition is stronglyweathered mud-stone purple. Slide the Jurassic bed under unified pearl blunt group mudstoneprimarily, local clip has sandstone, the current situation owe stability.Of deformation and failure of the landslide in the main controlling factors of the system andinducing factors analysis, judge the landslide the cause of formation mechanism, and establishedthe mathematical model, from two aspects of the qualitative and quantitative stability of landslidemade a judgment, detailed information below:①"Yang Ja Gou" weak deformation sectionWhen the judge as basic stability of landslide macro, through the stability calculation of theirregular engineering environment for the basic stability of the most adverse water storageengineering environment for owe stability；②"Chang shou" area porcelain factory for strong deformation sectionWhen the judge as owe stable landslide macro-is not stable, through the stability calculationof their regular engineering environment for the unstable, the most adverse water storageenvironment for the engineering stability；③The Wa Guang Yao street weak deformation section When the judge as basic stability of landslide macro, through the stability calculation of theirregular engineering environment for the basic stability of the most adverse water storageengineering environment for owe stability；The end of the article put forward two landslide treatment scheme, and a relative plan, and toselect one of them.①"Yang Ja Gou" weak deformation section: Two points for retaining cascade, the anti-slidepile in Chang li road use, at the same time, can protect Chang li road, also can prevent or becausethe human engineering activities in the landslide happened in middle cut out, to the Chang li roadthe following part, combining with the current respectively by means of gravity retaining wall forretaining. The following parts of wharf road, library water submerged area, using points order putslope management；②"Chang shou" area porcelain factory for strong deformation section: Two row anti-slidepile retaining, central library in landslides influence water boundary where a row of anti-slide pileset, and protect Chang li road and private housing, also can prevent or because the humanengineering activities in the landslide happened in subprime cut out, at the dock the set one rowhighway again anti-slide pile, to protect the wharf, the front of library submerged area water level,the points PianShi slope protection order management, in order to avoid the library bankrebuilding caused by water；③The Wa Guang Yao street weak deformation section: Using existing in the margin of theretaining wall repair retaining, leading edge library submerged area USES water level cent rankput up against sliding slope and retaining wall retaining. |
