COMPARATIVE ANALYSIS OF THE METHODS OF INTERNAL FORCE CALCULATION OF THE PRESTRESSED CABLE LATTICE BEAM FOR LANDSLIDE CONTROL

On the basis of the case study of a landslide prevention and control engineering work, a new model for design and calculation of the lattice beam suited to the layout of the engineering work is proposed.According to a comparative analysis of the results of calculation by using this model and the results of calculation by using the conventional Winkler elastic foundation beam and upside beam methods, the authors draw the conclusion that this model more closely conform to the actual manner of lo ad of the lattice beam.
