Test device of indoor model for reinforcing soft soil foundation by dynamic compaction

The invention belongs to the technical field of geotechnical engineering, and particularly relates to a test device of an indoor model for reinforcing soft soil foundation by dynamic compaction. As support of indoor model test data for existing dynamic compaction reinforcement is lacked, test accuracy cannot be guaranteed due to the fact that most indoor dynamic-compaction model devices which are applied to some extent are semi-model devices. Dynamic compaction is realized by dropping hammers at fixed points accurately under manual control, different types of model hammers and different visual and measurable drop distances are achieved, and accordingly single dynamic compaction capacity at different energy level can be provided. By the test device, internal deformation of soft soil under action of dynamic compaction can be observed in real time directly, and related data such as dynamic stress can be measured, so that defects of the prior art can be overcome effectively.
