| Along with our country vigorously carrying out the construction project and demand for transportation resources in the mountain area, the construction of the highway forward into the mountains. Design for highway line selection in the mountains, however, must through the complex terrain, certainly will encounter the problem of high filling and deep. When the construction of the slope in the complicated geological conditions, regional conditions, shall strengthen the management and monitoring of the slope and the research about the stability,including slope stability issues have become with earthquakes, volcanoes parallel global one of the three major sources of geological disasters. If, in the event of instability of slope landslide events will bring serious damage to people's life and property security, therefore,monitoring and stability analysis of slope has become an important topic in people's life or engineering construction.This paper takes the Guangfo Zhao highway as the research background, choose K171 +990 ? K172 + 210 section of the embankment on the right side of high slope as the research object, the simple analysis of the influence factors of slope engineering stability, for the project actual situation made the roadbed of reasonable design scheme; By means of finite element software GEO-SLOPE/W on the slope stability analysis, according to the calculation results, it is concluded that the slope is in unstable state under the natural state, after accordance with the construction technical measures for construction of embankment design scheme, the slope is in steady state. In order to ensure the correctness of the calculation results, using the Lizheng geotechnical software to verification, the software calculation results with the GEO-SLOPE/W calculation results are closer, illustrating the result of calculation is reliable. However, the software does not fully consider the impact of external conditions in the calculation process, in order to ensure the safety of the engineering, deal with the real-time monitoring of embankment slope, nearly six months monitoring data information reflects the slope is stable for the time being. In order to predict the future embankment slope deformation, FLAC3 D is adopted to simulation the fifth grade slope construction process, the other four slope simplify checking into the foundation, the results show that in the future, the post-construction settlement and slope displacement can satisfythe requirements of the specification. Comprehensive analysis, the slope is in a steady state. |
