Vibration reducing and isolating system and method
The invention discloses a vibration reducing and isolating system and method. The vibration reducing and isolating system comprises a liquid pumping and injecting device and a containing cavity formedin a foundation, the containing cavity is filled with a cobble layer, liquid is kept in the containing cavity, the liquid pumping and injecting device is used for injecting the liquid into the containing cavity or pumping the liquid from the containing cavity, the cobble layer is used for serving as the foundation of a building structure, according to the vibration reducing and isolating system,the liquid is pumped out or injected into the cobble layer in the containing cavity, the mass of the cobble layer can be changed, adjusting of the inertia force of the cobble layer and adjusting of self vibration frequency can be achieved, the bearing property of the cobble layer is basically not changed while the inertia of the cobble layer is changed, cobble particles and liquid between the particles carry out mutual effect, through the motion of the cobble layer, the resonance effect is exerted, liquid shaking friction energy dissipation is exerted, the vibration response of the building structure is reduced, the damping energy dissipation efficiency of the system can be greatly improved, the earthquake disaster can be effectively relieved, and the vibration reducing and isolating system has the groundbreaking engineering significance and practical value
本发明公开了一种减隔震系统及方法，该减隔震系统包括抽注液装置和设于地基上的容腔，所述容腔中填筑有卵石层，所述容腔中保持有液体，所述抽注液装置用于向所述容腔中注液或者抽液，所述卵石层用于作为建筑结构的地基。该减震系统，能够通过向容腔中卵石层抽注液体改变卵石层的质量，实现卵石层惯性力大小的调整和自振频率的调节，改变卵石层惯性同时基本不改变卵石层的承载性能，使卵石颗粒与颗粒间液体相互作用，通过卵石层运动发挥谐振作用和液体晃动摩擦消能，减少建筑结构震动响应，大幅提高了系统的减震耗能效率，有效减轻地震灾害；该减隔震系统具有开创性的工程意义和实用价值。
