隧道地震动力模型试验是在实验室中研究隧道结构地震响应和破坏机理的重要方法。其中,模型相似准则和相似参数的确定是正确进行模型试验的关键环节。以相似理论为依据,推导出隧道地震动力模型试验的相似准则,首先确定模型的几何相似比和弹模相似比,即可根据相似准则确定其余各相似参数。
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.
