On the basis of gathering data from previous study and researching the stabilization and reinforcing technique of the typical high slope in west approach road, through in-situ tracking investigation and monitoring to the west road, and by way of studying the interaction between slope body and anchoring structure, monitoring data, the result of grey prediction and fuzzy comprehensive assessment, and adopting the idea of integrating prototype investigation and indoor experiment analysis, mechanism analysis and simulation research method, safety factor analysis and interacting relationship study, in-situ monitoring and safety evaluation, and using the theories of engineering geology, geotechnique, rock body mechanic, finite element method and fuzzy mathematics, this paper studies the long-term safety of the typical high slope specially.

In the practice we have no special design of the approach slap , and the theoretical thereunder is not so reasonable. For example, when calculate the length of the approach slap, we adopt the permission differential change slap and settlement, without considering the height of road embankment filling , the form of abutment and the properties of the filling sort, so sometimes it is hard to eliminate the bridge head bump completely because of the disjoint, rupture or overshort of the approach slap, influencing the use of the road and bridge.
