Abstract: Underground structures are widely used in hydraulic structures, and seismic isolation and reduction of underground structures have always been important aspects of structural design. Installing seismic isolators on the middle columns of underground structures is a new type of seismic mitigation measure for underground structures. This article introduces the numerical simulation study of vibration table tests on typical structural models and middle column isolation models using FLAC3D. From the perspective of dynamic response parameters such as acceleration, stress, and strain, this study investigates the influence of rubber isolation on the dynamic response of structures and analyzes its isolation effect.
