Analysis On Slop Stability Of Mountain Highway

As the seriousness of the damaging effects of the slope , slope problem has been the focus of the engineering analysis and research. There are many ways in the problem of slope stability analysis , and the stability is affected by many factors. With large-scale construction of mountain highway, high fill slope is widely used .As a special engineering, high fill slope has complex nature of the filler,complexly environment of construction and difficult the serious consequences of the destruction and so on. Therefore, the high fill slope stability analysis and research has important theoretical and economic significance.In this paper, I will sum up the previous questions on the slope stability analysis and calculation methods referenced by practical engineering and related materials form the slope in a reasonably form ,and simplify model of actual projects. At the same time, modeling the slope model on the basis of experts suggested to analysis and comparison the two models .By using FLAC software ,engineering geological survey with detailed information and the parameters of the site construction process to simulate the high fill slope deformation and stability of roadbed .In this paper, finite element strength reduction compare with the actual engineering data to find the slope factor of safety ,and to determine a reasonable high fill embankment slope design in the form . Simulate the analysis of different slope angles of slope stability of slopes .To modeling and analysis to high fill slope, obtained from the simulation we get series of contours, we comprehensive analysis the high fill slope, concluded high fill slope stability failure of potential slip surface, comment on construction of proposed guidance. By using a single variable method to suppose the other factors influence of the high fill embankment slope ,change the reduction factor to analyze the impact of safety factor of slope. to maintain the overall stability of the slope it is very necessary to monitoring the displacement of pile in the high fill slope. Strengthen the monitoring and timely reinforcement the parts which trend to destruction of instability. At last, simplely modeling and analysis the tunnel mountain slope, verify its stability from the series of contours we get , comprehensive analyzed the slope of the tunnel. We get the sliding surface of the tunnel slope stability failure to comment on construction of proposed guidance.
