Research Skeleton Highway Slope Protection Technology

Slope protection as an important part of highway engineering, protection in variousforms, common slope protection framework form of traditional stone arched, herringbone,square shape, different protection forms vary on the slope protection effect. In this paper,taking Zhuzhou city in the construction of highway slope ridge tea as the engineeringbackground, building slope solid model, discusses the effect of different types of protection ofhighway slope protection, the theoretical results of the study can provide reference for futuresimilar slope protection, has a certain theoretical significance and practical value.According to different types of slope protection, building (stone arch skeleton, sewingprecast arch skeleton, sew a button precast arch skeleton) three slope solid model, load testsare done on the slope of the entity model, the data analysis under the same pressure slopeunder the effect of skeleton key point stress, strain and displacement changes on the top of theslope through test, comparative analysis between different slope protection framework typekey points of difference of stress strain and displacement variation. Secondly, in theconstruction of expressway slope ridge tea (flat seam precast arch skeleton) on-sitemonitoring, displacement analysis of slope in the deposition process and the stress situation,combined with the indoor experiment and outdoor monitoring, comprehensive analysis ofdifferent protection framework for slope protection effect.Through the analysis, the (stone arch skeleton, sewing precast arch skeleton, sew abutton precast arch skeleton) along with the increase of the load, three schemes of transverse,vertical, oblique extension strain increase.Three schemes based on physical model experiment shows, in loading and unloadingprocess of three schemes are obvious from the load effect, the closer, with the increase of theload displacement changes more.Comparative analysis on the loading process by three schemes, the vertical strain,oblique, transverse strain strain variation of different arch, sew a button is other excellent.In a joint framework protection model of monitoring data analysis of the stress anddisplacement variation analysis of arch flat, due to the construction site conditions andweather change is complex, the relative experiment of indoor model test results, has certaindifference, should be considered in practical design process of settlement is influenced by theenvironmental factors influencing the construction conditions and slope.
