Loess landslide is widely developed in eastern Qinghai,causing great harm to people's life and property。Qinghai province OK La landslide occurred in the upper Pleistocene period,the number of acres of buried farmland caused great economic loss; in recent years,along with the influence of rainfall,landslide,slope deformation,obvious signs,sliding rear is likely to produce local collapse,pose a threat to the front of slope farmland。Therefore,this study on OK La landslide,to summarize the loess landslide formation rules,to achieve the purpose of disaster prevention and reduction has far-reaching practical significance。The Qinghai province OK La landslide as the research object,in the ground survey,mapping and engineering exploration,obtained from various data OK La landslide as the main method; analyzed various factors affecting the formation of landslide,the Swedish slice method and the simplified Bishop method for slope stability are calculated,results show that Sweden the methods of calculating results accord with actual,the landslide is in steady state。In summary,this study draws the following conclusions:(1) landslides in the study area is located in the West Valley on the left bank of natural hill slopes,the slope by rainwater infiltration,collapsible loess,the loess landslide formation rock softening。(2) by comparison of Sweden slice method and the simplified Bishop method calculation found,Sweden slice method has more reliability。(3) the landslide at present although is in stable state,but in a variety of adverse conditions may be unstable,suggestions for prevention and control
