Abstract: In order to solve the similarity relation between the model and the prototype, based on the theorem of E.Buckingham ?, the dimensional analysis method is used. Using deduced similarity relation, the model test of column-net structure is carried out for the design and the manufacture with the field engineering practice. Model test results show that it is feasible for using the dimensional analysis method to deduce the similarity relation between the model and the prototype. The settlement curve of flexible arch likes the shape of net sling. The strain of geogrid increases with the structure heightening and cyclic loading time increasing; and it increases more quickly before the formation of soil arch than after ones.

Key words: model test, similarity theory, flexible arch, column-net structure
