Multi-layer earthquake fortification stop block based on V support

The invention relates to the field of building bridge construction and structural anti-seismic and anti-impact safety protection, and discloses a multi-layer anti-seismic fortification stop block based on a V-shaped support, which comprises a novel anti-seismic V-shaped support and a reinforced concrete stop block comprising the V-shaped support. The V support is designed according to a control differential equation derived by a'uniform plastic distribution model 'provided by the invention, and the reinforced concrete stop block internally comprises a specially designed reinforcing steel bar network which can be combined with the V support to realize multi-layer earthquake fortification. With the anti-seismic standard in China as the design reference, the V-shaped stop block ensures that a protected structural system is in a completely self-recoverable elastic state when the seismic load is smaller than the E1 fortification standard, and only residual deformation repaired under the condition that the structur
