Analysis On Stability Of Fenhe Reservoir Banks Slope And Its Characteristics

The importance of saving water reservoir water control project, in the flood disaster, drought irrigation and water resources utilization, protection of ecological environment construction, develop the national economy plays an important role.Fen River Reservoir in Shanxi Province in the Fen River in the late 50's built on a large-scale water conservancy projects, water storage has been 40 years running. Fen silt storage capacity currently has 330 million m3, accounting for sediment retention storage capacity of 95.68 percent, and the occupation of useful storage capacity 048.1 million m3, construction of the existing storage capacity only when the first half. Reservoir serious collapse, not only reduces the effective storage capacity, water pollution, and also damaged the reservoir bank topography, reduce the library side of arable land surrounding the reservoir directly affect people's production and life normally. To prevent the bank slope to collapse, reducing reservoir sedimentation, maximize the overall efficiency reservoir very important research significance.In this paper, a lot of access to foreign literature, summarized previous research on the basis of reservoir bank slope, through on-site field Fen Reservoir Bank survey, known mostly for the Fen soil reservoir bank slope, the vertical by loess joint development by the collapse of a collapsible and the impact of waves in the water immersion and water scour the role of such factors, the Bank Rebuilding rather serious. Border development of an unstable slope 6, slide 6. Based on the investigation at the scene, the paper on the formation mechanism of the collapse of the Bank Slope discussion of the stability of reservoir banks that mainly affected by water level change and wave effects. At the same time freezing rain and further accelerate the bank rebuilding process, on the slope stability of a threat. In the limit equilibrium analysis using Slope Fen Reservoir on the bank stability analysis carried out, that the Fen River Reservoir Western banks were stable, prone to collapse and have produced a small likelihood of landslides; and reservoir East Coast due to subsidence of the surface, vulnerable to ground subsidence, landslide-prone sites is; when the bank slope is less than 3m high, the bank slopes stable.In this paper, through the work of the Bank Slope of geological disaster, mainly made to take soil and water conservation, slope and slope combination of prevention and treatment.
