Shunjiang Residential Quarters Of Fuling District Landslide Stability Analysis And Treatment Measures Research

Abstract:Lanslides are most common disasters with the characters of widely distributed,frequently occurrences and large damage. Not only do they seriously threaten people’s lives properties and engineering safety,but will cause serious lose once slide. In the Department of The Army of Shunjiang area of Fuling, the soil roof caving phenomenon happened, the front landslide collapsed,and the back of landslide cracked which seriously threatened the safety of the Department of The Army of Shunjiang area.Once slide happened, it would threaten the lives and properties of1182,damage to building area of55100m2, destroy the road of0.6km, cause the lose of properties of72900,000.So it raise the attention of the government and the society from all walks of life to it. Although emergency measures has effectively control the disaster disk, temporarily stabilize the landslide, but the emergency works cannot eliminate the landslides fundamentally. Therefore, it is necessary to develop comprehensive research on the landslide stability and management engineering design.Taking the landslide of shunjiang area of fuling as study design,the paper comprehensively summary the topography, lithology, geological structure,hydro-geological conditions and meteorological characteristics in this area based on the geological environment in the landslide area. Though on-site survey mapping,geophysical prospecting and indoor and outdoor experiment, the characteristics of Multi-resolution and block and the deformations characteristics, analyzing the formation conditions, and in influencing factors the landslide, exploring the formation mechanism of the landslide. Engineering geology analysis and limit equilibrium method and numerical analysis are combined to evaluate the current steady-state of the landslide a qualitatively and quantitatively. Our achievements are as follows: (1) By analysis of the topograghy and geomorphology, body strycture, geologic,strate tock,surface water and groundwater etc. Draw along the Shunjiang landsild for a shallow soil landslide goes on type landslide, in peristalsis stage; Among them A subprime landslide of traction type landslide, B, C two subprime landslide goes on type of landslide, are in sliding stage.(2) The limit equilibrium method and numerical analysis of landslide in two conditions of the stability analysis, Calculated the natural state landslide stability coefficient is1.06-2.03, precipitation and earthquake conditions for0.92-1.09, The results show that the natural condition I landslide is basic stable state, heavy rains condition Ⅱ is in not steady-owe stable state.(3) Shunjiang area of fuling landsild’s Control project Level for Ⅱ level, According to the difference stability of landslide paragraphs and the different geological conditions, Shunjiang landslide’sPrevention and control engineering measures to use multilevel anti-slide pile retaining、Local area cut party and reducing load (C subprime landslide)、Local filling press foot、(front2-2’landslide section)、 Revetment engineering (concrete lattice and planting trees grow grass slope protection) and drainage engineering management measures to control.(4)Through the Shunjiang landslide stability analysis and treatment project design research, Is not only beneficial to the landslide regulation, will also be similar landslide stability analysis and providing reference and prevention and control.
