| Bedding rock slope refers to the tendency of rock slope which is excavated shares thesame strike and dip with layered levels. Engineering projects have proved that the accidentcaused by rock bedded slope, which led to more problems and great harm. Bedding rock slopestability is affected by many factors, such as the rock structure, rock features, groundwater,blasting power and earthquakes, which have also become the roadbed design difficulties.As for rock bedded slope which weak structural layer contains, Instability often happensalong the slippery slope. Firstly, through data collection and field surveys along the Shi-yan-Tianshui highway, analysis the influence of rock bedded common factors and the failuremode of slope stability. Then making qualitative and quantitative analysis on the sensitivity ofrock bedded slope based on single factor and orthogonal design method. Through the finiteelement analysis software, selecting the typical rock bedded slope model, making stabilityanalysis when the geometry and mechanical parameters of slip change. Finally, based onSPSS statistical analysis software, using regression analysis, fitting regression relationshipbetween safety factor, the amount of deformation, stress and strain fields and slip zone thick-ness, angle, cohesion, internal friction angle, the elastic modulus and Poisson’s ratio.In the actual slope engineering, the designs and protective measures of bedding rockslope are always not targeted systematically, if not handled properly, it will bring great losses,on the contrary, if too conservative, it will led to a waste of resources. Through the sensitivityanalysis of bedding rock slope based on poor analysis and variance analysis, the sensitivity ofvarious factors on slope stability can be done under qualitative and quantitative analysis andmake sorting. In terms of governance and optimal design of bedding rock slope, it can bemore specific, then taking the corresponding control measures. Therefore, it will have a cer-tain significance on the aspects of safety, efficiency, and economic for the protection of bed-ding rock slope. |
