“…The shear modulus ratio of the soil body 𝐺/𝐺 𝑚𝑎𝑥 and damping ratio D are the key parameters in the equivalent linear analysis. For sandy soils, this study uses the 𝐺/𝐺 𝑚𝑎𝑥 ~ 𝛾 relationship curves as well as the D~𝛾 relationship curves [26][27][28][29] for the equivalent linear calculation. Figure 12 shows the curves for the sandy soils.…”

In this study, based on the actual project in Dalian, the dynamic interaction of the double tunnel sand bridge pile system (SSSI) under earthquake action is studied by shaking table test, and the dynamic response laws of the structure and site are obtained, which are compared with ABAQUS numerical simulation. The Kelvin constitutive model subprogram is introduced into the numerical model, and the equivalent linear method is used to deal with the nonlinear problems of sand in the calculation process. The experimental results are compared with the results obtained using the numerical model to verify the reliability of the numerical simulation. Based on this, eight working conditions are designed, and the interaction law between the structures in the system is investigated through a comparative analysis. The results showed that the tunnel amplifies the dynamic responses of the bridge pile, adjacent tunnel, and far field, while the bridge pile attenuates the dynamic responses of the side tunnel and far field; the presence of both the tunnel and bridge pile increases the internal force of the adjacent structure, and the peak internal force often occurs near the intersection of the structure or at the pile–soil interface.
