Pile-in-row structure of periodic built-in resonators for vibration isolation
The row pile structure comprises hollow steel pipes, the hollow steel pipes are arranged in a soil body in a square lattice shape, a top packaging cover is arranged above the hollow steel pipes, and a plurality of resonator structures are evenly arranged in the hollow steel pipes. The hollow steel pipes are arranged in the soil body to form a row pile structure; due to the fact that the hollow steel pipe structure has the scattering characteristic and the resonator local resonance type seismic metamaterial can achieve ultralow-frequency vibration isolation, the row pile structure-resonators are periodically arranged to form the vibration isolation barrier, the barrier can obtain an ultralow-frequency band gap, vibration generated by moving loads is isolated, and the vibration isolation effect is improved. Therefore, the vibration damage to the surrounding environment caused by the train running at a high speed is avoided.
本发明涉及一种用于隔振的周期性内置谐振器的排桩结构，包括空心钢管，所述空心钢管成正方晶格状排列在土体内部，所述空心钢管上方设有顶部封装盖，所述空心钢管内部均匀设置若干谐振器结构，所述空心钢管在土体内部形成的排列为排桩结构；通过空心钢管结构具有散射特性以及谐振器局域共振型地震超材料可以实现超低频隔振的特点，通过将排桩结构‑谐振器周期性排列形成隔振屏障，该屏障可以得到超低频带隙，实现对移动荷载产生的振动的隔离，从而避免了高速行驶的列车对周围环境产生的振动破坏。
