“…In the vibration table test of underground structures, laminated shear model boxes are widely used [23] According to Buckingham's π theorem [24,25], length, modulus of elasticity, and acceleration are selected as the basic physical quantities for the design of the model structure similarity relationship. Considering the size of the model and the convenience of the According to Buckingham's π theorem [24,25], length, modulus of elasticity, and acceleration are selected as the basic physical quantities for the design of the model structure similarity relationship. Considering the size of the model and the convenience of the sensor arrangement, the similarity relationship of each physical quantity is obtained, as shown in Table 2.…”
