| With the large-scale implementation of the expressway project, more and more highwayslope engineering need to be addressed. Due to the limitations of the technical standards of thegeological features, linear, longitudinal, Inevitable appear a lot of high fill ferret out roadbed,especially a large number of cutting high slope diseases are caused by the excavation. Slopestability issues have become increasingly prominent, While domestic highway slope designand monitoring lack of mature theories and norms, therefore, how to safely and effectively andeconomically design and monitoring the high slope of the highway become the research topicsof the high slope engineering.This paper takes cutting high slope of Boluo to Shenzhen section in Yuexiangexpressway as the research object. First，high slope type of deformation and its influencingfactors are analyzed and summarized. Second, according to the natural elements of the study,analysis its deformation mechanism and put forward design ideas, and then select therepresentative cross section for slope stability calculation, and then determine design program.Finally, this high slope is designed detailedly in line with the principles and norms of the slopedesign.More and more security problems of the high slope engineering need to ensure throughmonitoring, the results of monitoring can be used to test the accuracy of the design in order toimprove the design level. This project using its own characteristics conduct the slope surfacedisplacement monitoring and slope deep displacement monitoring, then draw displacementtime relationship diagram collected by the on-site monitoring data. According to the slopedisplacement-time profile, the stability of this slope is judged by the macro signs anddisplacement rate. Finally, some suggestions of the later period monitoring are gave on thebasis of the characteristics and circumstances of the high slope. |
