Research On Design Of Prestressed Anchor Cable Lattice Beam In Slope Engineering

Along with the national infrastructure construction investment increasing, in nationalhighway and water conservancy and hydropower project will form lots of slope, for the slopeengineering management put forward higher technical requirements. Prestressed anchor cablelattice technology is combined with the prestressing anchor technology and lattice beamstrengthening method, result of a new type composite light slope shoring reinforcementtechnique. In recent years high cutting slope, water conservancy and hydropower slope,industrial and civil building projects get more widely used in. Therefore, the theory of theprestressed anchor cable lattice beam and technology of the design of the research is veryimportant.(1) Prestressed anchor cable lattice in the slope engineering has extensive applicability.Slope body structure is complex, and the destroy form also form is varied. In practicalengineering almost don’t have the same slope treatment project, so can’t according to the pastslope of governance mode, to finalize the design of large and medium-sized slope engineeringdesign. The management of slope engineering design should be separatly designed. Also,lattice of prestressed anchor in slope engineering management application or not, and shouldbe based on the specific worksite the concrete circumstances.(2) This article takes the theory analysis and numerical simulation in two ways, and thecombination of prestressed anchor cable lattice beam will first divided into single-girder, thenode force of prestressed anchor in lattice beam is assigned reasonably, and to be simplifiedconcentrated load. The complex space lattice anchor structure effect is simplified analysis oflattice single girder on foundation by the different concentration load. And then to design theanchor often uses in lattice design theory is summarized, through the calculation results andnumerical simulation result comparison, we can find the sound calculation theory method. At the same time for the design of prestressed anchor in the important parameters of designoptimization analysis.(3) Finally, combined with a slope engineering strengthening management, according tothe proposed design method in this paper on the detailed design. And the related parametersfor the prestressed anchor design optimization. Finally on the slope of the specificconstruction and management, numerical simulation and calculation. The results show that theslope in take the reinforcement measures, slope stability coefficient obviously improved andmeet the standard safety requirements.Through the above research of the paper, and hope to have the certain reference value toslope control project with the prestressed anchor cable lattice beam.
