Research Of High Slope Stability Analysis And Reinforcement Measures

Deformation of high slope stability problem widely exists in large water conservancy hub, in order to further analysis for the deformation of high slope stability is calculated, and the study of high slope reinforcement measures, provide the basis of the important support for the design of water conservancy construction, the article carried out the study of related issues.These articles relate to the slope stability in narrative theory and research status,relevant to the calculation method of stability analysis and slope reinforcement method, after a brief introduction to a large water conservancy hub as an example in the research of the system. This paper combined with the previous analysis and field geological reconnaissance, geological data to get the water conservancy hub in the right bank slope, except the F9 fault on the right bank slope stability, control the play development also have a lot of slope unloading fissure, combined with the other structure faces of slope in the development, has formed a large number of dangerous rock mass, and affect the normal operation of the right bank slope of a very adverse factors. Articles use two-dimensional limit equilibrium methods, on the right bank slope in the natural conditions, construction period, the normal storage level conditions and natural conditions and the normal storage level in earthquake condition under the condition of stability analysis and calculation. Then according to the 3d finite difference program FLAC-3D wall dam and concrete face rockfill dam type two kinds of dam construction on the difference of the right bank slope stability analysis,and we consider the influence of the F9 fault. And in view of the supporting measures are put forward, the large-scale geotechnical general software FLAC-3D simulation slope supporting effect, and optimize the supporting plan research.Two-dimensional limit equilibrium calculation results show that the stability safety coefficients calculation section under different working conditions meet the specification requirements. Slope excavation, such as DAMS, water storage condition of the simulation results show that in addition to fault near the slope surface is exposed and excavation surface, slope displacement distribution uniformity, conforms to the general rule, the plastic zone distribution range is small, there is no clear plastic transfixion area, shows that the slope overall stability is good. To put forward the right bank of the high slope support measures of slope reinforcement effect are analyzed innumerical simulation, through the calculation results show that the F9 fault handling and on the slope reinforced by pressures anchor cable can have good reinforcement effect, the F9 fault treatment combined with 1860m~1910m within the scope of prestressed anchor rope supporting effect, the optimal comprehensive supporting.
