Model Tests of Dynamic Consolidation and Its Progress

The theoretical basis of experimental design for dynamic consolidation model test was briefly analyzed,and the similarity conditions of dynamic consolidation model test were discussed.On the base of detailed derivation of similarity criterion carried out,the concepts of similarity dynamic consolidation model tests and non-dsimilarity dynamic consolidation model tests were put forward.The model box size,the selection of proportional similarity coefficient,instrument precision,data processing and other issues in dynamic consolidation model tests had severely restricted the research and application of dynamic consolidation mechanism.As in-depth discussion and analysis on these issues unfolded,the paper suggested that in the model test we should improve the sensitivity and accuracy of the data acquisition instrument,build gray system model to enhance data processing accuracy and so on.
