Study On The Beam Ofprestressed Anchor In The Slope Suppotring

In recent20years, with the development and utilization of the natural world,a growingnumber of transport infrastructure, mining and utilities, many of them are destroying theoriginal geological structure. When the mountain can not be avoided, it formed a large numberof slope, if the governance of these slope is improperly, it can cause serious of geologicaldisasters,and losses people’s lives and property. Pre-stressed anchorage cable lattice beam is anew high slope reinforcement technology,and it applications in a variety of side slope protection.It mainly applied to the loose surface rock and soil slope broken landslide. As The theorybehind the practice use. This dissertation based on the case study of the slope control project forjiuhua mountain cableway,using a combination of theoretical analysis and finite elementvalidation.The paper researchs the prestressed anchor cable and ground beam stress analysis,internal force calculation, the calculation of earth pressure of the soil mass under the beam,prestressed anchor cable ground beam under the action of stress field variation.It is determined in the optimized design of the pre-stressed anchorage cable the calculationof its installation angle，anchor length and spacing，and analysed also the force distribution ofpressure pre-stressed cable with the finite element software．The ground beam designfocused on the calculation of earth pressure and ground beam internal forces.The WinklerElastic foundation beam method to calculate the beam internal forces is relatively simple andcan meet the need of engineering,it’s a good method of calculation of the ground beam internalforces.We must pointed out that the internal force calculation points to the anchor cable tensionstage and long-term stage.Finally, slope protection works for the B1collapsed segment of the Jiuhua mountain cableroad, given a specific design program, the dissertation puts forward a specific design schemeand applies the large—scale general finite element program ABAQUS in the numericalsimulation of the reinforcing effect of this scheme，providing slope stability factor afterreinforcement and validating its rationality,with the hope that practical conclusions call be drawfrom the above analysis for the project．...
