Visual multipurpose loading device suitable for tunnel vibration table test

The invention provides a visual multipurpose loading device suitable for a tunnel vibration table test. The loading device comprises a steel bracket, a steel spring, a longitudinal rib plate and a component force plate, the steel support is composed of a framework standard part, an arc-shaped steel plate standard part, a transverse standard part and a bottom plate standard part. The steel support is fixedly connected through a longitudinal rib plate. And one end of the steel spring is fixed on the steel bracket, and the other end of the steel spring is connected with the outer side of the component force plate. The visual multipurpose steel support loading device suitable for the tunnel vibration table test is used for simulating the vibration table test of a tunnel structure and replacing a traditional geotechnical box, and the device is novel, reasonable, reusable and capable of macroscopically observing the seismic response of the tunnel structure. 本发明提供一种适用于隧道振动台试验的可视化多用途加载装置，所述加载装置包括钢支架、钢制弹簧、纵向肋板以及分力板；所述
