Abstract
The simulation analysis model of the concrete experimental foundation platform is constructed by the method of three-dimensional computer-aided design (3D CAD) and three-dimensional computer-aided engineering (3D CAE). The influence of the slotting depth and width on the concrete structure’s vibration isolation performance is analyzed in detail. The results show that as the slotting depth increases from 0 m to 4 m, the total vibration acceleration level of the concrete inner side structure decreases by 12.27 dB. The vibration isolation performance of the foundation platform is highly sensitive to the slotting depth. As the slotting width increases from 0.5 m to 2 m, the total vibration acceleration level of the concrete inner side structure is always maintained within the range of 8.8 dB–8.9 dB. The total vibration acceleration level of the foundation platform changes little. Vibration isolation performance shows low sensitivity to the slotting width.
