Large-scale vibration table test loading device suitable for passing through various stratum tunnels

The invention discloses a large-scale vibration table test loading device suitable for passing through various stratum tunnels, the loading device is formed by assembling and connecting a plurality of sections of test supports along the longitudinal direction, each section comprises a vibration table test support, a spring and a component force plate, one end of the spring is fixed with the vibration table test support, the other end of the spring is fixed with the component force plate, and the other end of the spring is fixed with the component force plate. And the other end is fixed with the component force plate. According to the invention, the loading device is built on the vibration table, and the loading device is rigidly connected with the vibration table, so that the displacement input effect of the vibration table can be completely transmitted to the tunnel model through the spring. The loading device can be assembled into different cross section shapes such as a round shape, a square shape or a hor
