Research On Evaluation Of The Stability And Reinforce Scheme Of The Landslide In The Left Of One Station Roadbed In Pengyou Road

According to the Landslide in the left of K11+721~K11+805 roadbed in PENGYOU Road, this artcle dwell on the slope along with water and analyzes the characters and deformation of soil and rock, It also answers how to determine all the data of the slope and evaluates the stability of the slope On the ground of the data, it put out some useful design ande deformation plan to reinforce the slope. The method that is used in this article is useful to the similar slide.In this paper, the process of landslide margin of first place for the post-deformation, the weight under stress and heavy rain after the lower edge of the stability of soil sliding forward, to promote the leading edge of the soil. The North West wall of soil overhead, the bedrock surface along the dip, the direction of production to the gully slide; south east wall of the soil after the overhead for the gullies along the direction of bedrock; landslide margin after the formation of scarps, producing many secondary landslide and unstable rock and soil; landslide front slipped south gully of its landfill, the telescopes to ditch the other side of the foot of the landslide to stop sliding. The Road due to construction in the intersection of two gullies, landslide blocked in the south west side after sliding, partial turn, to the west side of the Road sliding direction. Special deformation of landslide using the Lagrangian method to simulate the landslide will more truly reflect the actual situation.The main points are briefly summarized as follows.1.The regional geological environments of slope are analyzde, and physical mechanics parameters of rock are gotten. And these parameters are necessary to stability analysis and reinfoce method.2.The structure, scope and scale of slope body are analyzd, and the regulation of slope beginning and developing is put forward. First use of limit equilibrium transfer coefficient method to calculate the stability of the landslide analysis, lagrangian method and then use the numerical simulation of the landslide, landslide by numerical analysis to simulate the deformation and stress conditions.3.On the bases of above-mentioned research and priciple of reinforcing slope, it put forward overall reinforced scheme.4.Analysis of control arising from social and economic benefits program.
