To find a more suitable soil dynamic constitutive relationship model for ground fissure sites so as to accurately study the dynamic response law of different distributions of soil layers in common sites and ground fissure sites

the soil shaking table test for ground fissure sites was designed and completed with the f4 ground fissure site in Xi′an as an example. Then

the secondary developed equivalent linearization model

boundary surface model

and Mohr-Coulomb model were established

and numerical analysis models were compared with experimental results. Finally

ABAQUS numerical analysis was carried out on ground fissure sites and normal sites under six working conditions with the boundary surface model as the constitutive structure

and the influence of ground fissure sites distributed in different soil layers on the dynamic response of soil was explored. Results show that the soil had a large plastic deformation under high earthquake intensities

and the boundary surface model was a suitable dynamic constitutive model for soil in ground fissure sites. The seismic waves could be amplified in common sites and ground fissure sites

but the effects were different under different working conditions. The ground fissure sites all showed acceleration amplification effect

and the upper and lower wall effect was similar to the shape of “八”. The maximum influence range of the upper wall was 11 m

and the maximum value of the lower wall was 9 m. The research results can provide reference for the seismic design and engineering application of engineering structures under the ground fissure environment.
