Study On Stability And Treatment Of Huoshanpo Landslide

With the development of social economy, highway construction in mountain areaincreased year by year. But excavation and fill of natural slope during the building toembankment, inevitably disturb the balance equilibrium condition of the slope.So it oftencauses slope instability, or even landslide when rainfall, bad geotechnical characteristics.Therefore, the research on process of landslide stability and characteristics of geotechnicalsliding has a positive effect on the prediction of slope stability’s tendency in the future andlocal economic development. It also can provide design basis for subsequent slopemeasures engineering, determine reasonable scheme to control it, offer useful experienceto the similar cases. In this paper used Huoshanpo landslide as the engineeringbackground of landslide, study the related problems such as the landslide mechanism,stability analysis and treatment measures and so on.First, this paper introduces the general situation of the Huoshanpo landslide slopeengineering, including natural conditions, geological conditions and so forth.Combiningthe wild field investigation data, the author analyse the system of landslide mechanismthoroughly.Based on the geological environmental conditions and the analysis of the causes oflandslide, research the landslide stability analysis method and combining indoorgeotechnical experimental data, firstly work out landslide stability safety factor utilizedthe limit equilibrium method and Sarma method of landslide stability theory analysis inthe two cases: the dead weight and heavy rains. Then simulate landslide with Lagrangefinite element numerical method to obtain landslide displacement field, stress field and thedistribution of the plastic zone through the simulation results. At the same time, Graysystem used to forecast the trend of landslide. The landslide stability analysis results andthe on-site investigation results are comprehensive contrast, for landslide control providesthe more scientific and reasonable theory basis.Finally, in the stability analysis of landslide data as the theory basis, combined withreasonable scientific landslide treatment principles, gives a brief landslide measures andrecommendations. At last the measure of the anti-slide pile on the numerical simulation control effect is analyzed to show that the measure is effective.
