Study On The Analysis Of Slope Stability And Governance Program In Panjizhai

Landslide is a highly destructive disaster, which is widely distributed around the globe. The Lives and property of citizens are suffering from the threat of landslides, which belong to 70% mountain area of our land. It's taking government departments and technical personnel attentions to curb Landslide in effective and economical governance.Firstly, this article introduced transfer coefficient in the stability evaluation, and summarizes the numerical simulation modeling approach. Secondly, this article lists the design calculation steps of retaining structures including retaining walls and piles. Finally, this article give the following several conclusions in the background of landslide governance in Panjizhai, Gansu Province.(1) According to survey data, this article analyses the engineering geological conditions of the Panjizhai landslide, finds out the landslide sliding mechanism, and summarizes the main factors affect the slope stability.(2) By using the limit equilibrium method for landslide stability calculation in different conditions, and using finite element GeoStudio software for modeling the comparative test of the stability, this article determine the role of landslides stability in the rain or seismic force.(3) This article calculates the thrust of the landslide and gives the reasonable spacing between piles by soil arch theory According to Panjizhai landslide topography and geological conditions, this article proposed a variety of governance options for analysis and comparison. And the final choice of governance program is piles with drainage and slope protection. Finally, Feasibility is determined by numerical simulation in the effect of landslide governance with finite element software.
