| In recent years, with the rapid development of highway construction, Shaanxi, Gansuand other provinces, there has been a large number of high loess slope. Because of specialtopography, soil properties, lead to the formation of landslides and collapses after slopeexcavation. In addition, serious spalling and erosion of the loess slope, these affect the safeoperation of the highway.In this study, based on the projects that Analyses and countermeasures of theTongchuan-Huangling road high loess slope and science and technology issues in thewestern traffic loess area highway slope protection technology research. Analysis of asystematic investigation of Shaanxi and Gansu has built roads high loess slope, Accordingto the conditions of the slope in which the topography and loess traits, High loess slopegrouped into six types of geological structure of the model. For different modes of thestructure, take a different slope design and preventive measures.Loess slope stability analysis, analysis of the stability of a variety of factors,compared to a variety of calculation results. Summary of the mechanism and the applicableconditions of the various slope protection measures. Reinforcement measures for slopestability, Lists the design and calculation method of the piles, retaining walls, soil nail wall,anchor frame beams and other commonly used measures and their conditions of use; Forslope stability protection measures, summed up the mechanism of action and the applicableconditions of the retaining wall, skeleton and slope protection measures. This papersummarizes the loess slope drainage, Analyzed and compared according to the differentnatural conditions of the loess areas of engineering and plant protection, the proposed slopeprotection measures should promote a green protective type of plant protection,"Protectiontechnology, meteorology, soil coordination, according to the slope geological model to setthe type of engineering protection" principle of slope protection and protective design. |
