Abstract:Due to the limitation of natural conditions, to build roads across the northern tableland, it is necessary to overcome a series of problems, such as large elevation difference, many geological hazard risk points, large filling and excavation, and serious destruction of natural sites. It is hard to reach the construction expectation if the design concept of conventional municipal road and straightness planning is used. How to span the height difference and realize the crossing of the two places, at the same time to meet the requirements of capital and safety engineering has become a must to overcome the difficulties. In view of this, through the design concept of combining the route selection with site utilization, comprehensively utilizing the site, and combining the slope treatment with natural strata, the design scheme of combining the road alignment with aesthetics, combining the slope treatment with disaster prevention, and under the complex geological conditions, specially treating the pebble interlayer slope, combining the high slope with landscape, and combing the engineering construction with ecological environment protection is adopted, which provides reference basis for route selection and slope treatment under complex geological conditions in the future.
