The basic characteristics of vertical and horizontal displacements of the ground surface cannot be effectively simulated, and the obtained results of dislocation characteristics of ground rupture are inaccurate, when using a Trimble GX 3D ground laser three-dimensional scanner to analyze the dislocation characteristics of normal faults in interbedded cemented soil. To address this issue, this paper proposes a new method to study the dislocation characteristics of seismic surface fractures of normal faults in interbedded cemented soil. First, the elastic dislocation model of the earthquake surface was constructed, and the three-dimensional fault characteristics of the normal fault in interbedded cemented soil were analyzed to obtain the surface dislocations. Surface rupture dislocation characteristics of normal faults in interbedded cemented soil were then studied through the centrifuge test. The experimental results showed that the proposed method can effectively analyze the dislocation characteristics of the seismic surface fractures of normal faults in interbedded cemented soil. The fracture depth of the fracture point in the middle and lower parts of the soil model were 22.4 m and 33.4 m, respectively. The fracture was deeper with the fracture point in the lower part of the soil model.
