| 英文摘要 | A deep underground laboratory is an important research site for fields such as particle physics, astrophysics and cosmology, which require not only sophisticated technology and precision instruments but also stable and interference-free research environments. Ground motion can introduce interference with some precision in-struments, causing the instruments to fail to work normally with the highest accuracy and even causing serious errors. Therefore, effective vibration suppression measures play a vital role in underground laboratory research. Based on the shielding effect underground structures have on ground motions, a shielding wall is proposed as a new vibration suppression method. By simulating the ground motion characteristics of various models (back-ground models, excavation models, and backfill models) in the Jinping Underground Laboratory, the high-efficiency vibration suppression effect of a shielding wall was demonstrated. The influence of different back-fill conditions on the vibration suppression effect of the shielding wall was systematically analysed, and a nonbackfilled shielding wall was determined to be the best vibration suppression option. Moreover, the influence of the length, position and angle of the shielding wall on its vibration suppression effect and the potential application prospects of the shielding wall were also discussed. Shielding walls enrich and develop vibration suppression measures, providing a new method for the prevention and control of seismic hazards in underground laboratories and surface buildings under dynamic load conditions. |
