Device and method for testing structural evolution in soil consolidation sample preparation process

The invention discloses a structure evolution testing device and method in a soil consolidation sample preparation process. The structure evolution testing device comprises a consolidation sample forming device, a loading device and a shear wave velocity testing device. The consolidation sample forming device is used for compaction sample forming; the loading device is used for applying a load to the soil sample; and the shear wave velocity testing device is used for measuring the shear wave velocity in the consolidation sample forming process. The scheme provided by the invention has the beneficial effects that the structural development of cohesive soil in the natural deposition process is quantitatively described by measuring the multidirectional shear wave velocity of the soil sample in the loading consolidation and unloading processes; and the structural evolution law and the anisotropic development of the structure of the soil body caused by the historical action of loading and unloading complex stress
