Abstract A structural dynamic test is an important research technique for evaluating structural seismic response mechanisms. The types of model boxes used to research the seismic response mechanisms of underground structures are mostly rigid, flexible and layered-shear, which have some defects and shortcomings. A new type of model box that is a coupling of static and dynamic modes and a new test method named the pseudo-static method are introduced in this paper and their effectiveness is validated by a dynamic test with a shaking table. A pseudo- static method is proposed to study the seismic response of tunnel structures. By comparing the results of the dynamic test and the pseudo-static test, it is determined that it is possible for the pseudo-static method to replace the dynamic test to some extent, which broadens both the testing method for this model box and the studying method for a model test of the seismic responses of tunnels.
