【Abstract】 Tunnel seismic model test is the important method to study the tunnel structure seismic response and failure mechanism in the laboratory.Among them,similar guidelines and parameters are key factors to model test.Based on the similar theory,similar guidelines are conducted,and then we can first determine the geometric similar ratio and the elastic modulus similar ratio,in the end,get the other similar parameters.更多还原
