With the development of the national economy, especially in the western development policy in the implementation of projects, railways, roads and urban infrastructure construction, such as the upswing in these projects are all related to slope stability problems. The slope stability analysis is a very basic project, but must pay sufficient attention to the issue, for a long time, the slope stability study engineering and academia has been a hot and difficult problem.This paper to Hongmei left medial landslides in the reservoir for the study, analysis of existing geological data and landslides cause on the basis of use of Morgan Houston -Price stability of the landslide calculated on the proposed governance programmes Landslide, and after treatment for slope stability analysis of the calculation results show that governance programme is reasonable. The main results of the studies and research:1 Yao'an County Hongmei Reservoir dam near the left bank of the medial mountain landslide topography, meteorology, hydrology, geological structure, stratigraphy structure, hydrogeological, and the adverse effects of the earthquake role of the geological engineering geological conditions, elaborated on the slope geotechnical physical and mechanical characteristics.2 Adoption of the geological and geophysical exploration data analysis of the information, basically mastered the landslides in the shape, composition and other basic features. Yao'an County Hongmei Reservoir dam near the left bank of the medial mountain landslide plane form a similar fan, landslide area of 78200 m~2, about 275.26×104m~3 size to large over-rock landslide.3 Yao'an County Hongmei Reservoir dam near the left bank of the medial mountain landslide mainly by the formation of terrain conditions, geological factors, rainfall, reservoirs factors factors, the formation of these factors is the result of the role.4 According to Morgan Houston - Price stability of the landslide, in a landslide that limit equilibrium~unstable state and creep stage, if continued development will be sliding development phase.5 Because of the uneven landslide, console side wall deformation has been cracking. Water Tunnel landslide has caused faults and console scrapped, and can no longer be used. According to the sliding of landslide dam spread to surge, dead water level as high as 1978.8m condition surge 27.2m, normal water conditions 1994.8m swells as high as 13.2m. Landslide middle and thrust into the enormous surge caused by the dam will pose a serious threat to security.6 Hongmei Mountain Reservoir landslide control measures should be for the construction of surface drains, excavation Adit as a supplement underground drainage, slope cutting by combining pressure in the overall management of feet.The landslides in the area, physical and mechanical indicators low, complex geological conditions, and therefore their specific research is very necessary. At the same time the study also makes it possible for future similar slope stability analysis and the engineering design of landslide control reference.
