Abstract

The invention discloses an assembling type variable rigidity model case used for a vibrating table test. The model case is composed of walls, a bottom plate and side pillars through splicing. The walls are formed by flexible connection of multiple transverse beams, multiple pillars, bottom transverse beams and enclosing plates through fasteners. The side wall of the model case is formed by flexible connection of multiple walls through the side pillars. The side wall of the model case is fixed on the bottom plate so that the model case is enabled to be formed. The bottom plate is rigidly connected at an external vibrating table. Side rigidity of the model case can be flexibly adjusted in the vibrating table test requiring simulation of a hard soil or soft rock site so that the model case is enabled to be suitable for the vibrating table test of the hard soil or soft rock site.
