Combined test model for fissure pre-forming in dynamics and statics similarity simulation test

The utility model discloses a combined test model for fissure pre-forming in dynamics and statics similarity simulation test. The combined test model is technically characterized in that a lower dynamics sample circular model, a middle dynamics sample circular model and an upper dynamics sample circular model are stacked on a convex disc base sequentially by matching of step tongues and grooves, and the convex disc base and each sample circular model are fastened and connected vertically through vertical clamping grooves and vertical bolts arranged on the side faces thereof in the same direction; each of the lower dynamics sample circular model, the middle dynamics sample circular model and the upper dynamics sample circular model is of a semicircle combination structure, and fastens and connects two semicircles horizontally through horizontal clamp grooves and horizontal bolts arranged on the side face thereof in the same direction; a plurality of pre-formed fissures are disposed in the middle dynamics sample circular model. By the test model, dynamics and statics standard samples different in height-diameter ratio can be made as required, the fissures can be pre-formed in the samples, and the combined test model is simple to operate and flexible in combination mode, the made samples are high in quality, and cost of the test model is saved.
