The Deduction of Similarity Relationships in Tunnel Model Test

Similarity relation has been studied on the basis of similarity theory in . Galongla tunnel shaking table model test The model test similarity criterion is deduced by equation analysis and dimensional analysis. The geometric conditions, boundary conditions, loads and materials are correctly simulated in the table test. Comparison has been finished from the curve of acceleration-time, spectrum feature, coefficient of acceleration and failure. The results from the tests coincide highly with theory values. The phenomena of failure and location also agree well. It shows that it is reasonable for the simulation relation.
