Anchor pier lattice beam node load distribution and lattice beam internal force analysis method and system

The invention discloses an anchorage pier lattice beam node load distribution and lattice beam internal force analysis method and system, and relates to the field of anchorage pier lattice beam structure analysis for slope reinforcement. Constructing a linear equation set based on the static balance condition and the deformation coordination condition of the lattice beam node of the anchorage pier on the Winkler foundation; each cross beam and each longitudinal beam are intersected to form a plurality of lattice beam nodes; the anchorage piers are located at lattice beam joints; the total load acting on each lattice beam node is distributed to the anchorage piers, the cross beams and the longitudinal beams which intersect with the lattice beam nodes by solving a linear equation set, and the load of each lattice beam node acting on the anchorage piers, the cross beams and the longitudinal beams which intersect with the lattice beam nodes is obtained; and according to the concentrated load obtained after node d
