Study On Static Dynamic Characteristics Of Carbon Fiber Cloth Lattice Beam Anchorage

As a mountainous country,China has many natural slopes,and the number of artificial slopes has also increased.Some of the slopes will occur under the action of natural factors,excavation and filling,resulting in landslide disasters.Due to the large number of slopes,the economic losses and casualties caused by landslide disasters in China every year.After the occurrence of landslide,it will also damage the surrounding environment,rock strata and infrastructure,which requires a lot of money,manpower and material resources to repair and support.Therefore,the research on landslide treatment is of great significance,and how to balance efficiency and economy in the treatment of landslide has become the focus of research.Therefore,this paper improves the failure mechanism of lattice anchorage system,puts forward the corresponding design optimization,and proposes a new type of carbon fiber lattice anchorage system,which verifies its feasibility through the combination of theoretical research and numerical simulation.The main research conclusions are as follows:(1)Based on the analysis of the failure mode of lattice anchorage system,the carbon fiber lattice lattice anchorage system is proposed,the soil and structure are optimized,the optimal design scheme of carbon fiber lattice structure system is obtained,and the calculation formula of the bearing capacity of carbon fiber lattice lattice beam is deduced.It has been proved that the optimized design scheme can ensure that the carbon fiber cloth plays the maximum role,give full play to its superior tensile performance,and improve the stability of the slope..(2)In the static state,the slope stability of carbon fiber lattice structure anchorage system is improved compared with the ordinary lattice anchorage structure,the deformation and failure of the soil is improved,and the deformation and internal force of the lattice beam and anchor rod are controlled,and the bearing capacity of the structure is increased.(3)in the dynamic state,the condition of lattice anchorage structure reinforcement slope soil and structure deformation is larger,using carbon fiber cloth optimal paste scheme of lattice anchorage system paste reinforcement,the slope of the soil and structure deformation and internal force numerical reduction,the slope stability increase,compared with the earthquake,carbon fiber cloth lattice anchorage system reinforcement slope under the rare earthquake,the slope stability effect is more obvious,that carbon fiber lattice anchorage system has good seismic performance.(4)through numerical simulation found that carbon fiber lattice anchorage system whether in static state,or earthquake,reinforce the performance of the slope is better than the lattice anchor structure,for slope stability and the structure of the bearing capacity have better,and based on the actual engineering case,comparing four carbon fiber cloth paste scheme,obtained the optimal paste scheme.
