Shock absorption and isolation system and method
The invention discloses a shock absorption and isolation system and a method. The shock absorption and isolation system comprises a liquid extracting and injection device and a pebble stratum with a certain size, wherein the liquid extracting and injection device is used for injecting liquid into the pebble stratum or extracting liquid, and the pebble stratum is used as a foundation of a buildingstructure. According to the shock absorption and isolation system, the quality of the pebble stratum can be changed by extracting the liquid and injecting the liquid to the closed pebble stratum, adjustment of the inertia force magnitude of the pebble stratum and adjustment of the natural vibration frequency are achieved, the resonance action and liquid shaking friction energy consumption are played through the movement of the pebble stratum, the vibration response of the building structure is reduced, the vibration reduction and energy consumption efficiency of the system is greatly improved,the shock disaster is effectively reduced, and the sand liquefaction phenomenon under the earthquake action of the natural pebble foundation can be avoided; by means of the device, the natural pebblestratum characteristic can be directly used, and the shock absorption and isolation effects of a tuned liquid damper are achieved; and the shock absorption and isolation system is suitable for different foundation conditions, is convenient to construct and good in energy consumption effect and has the creative 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体积一定的卵石地层，抽注液装置用于向卵石地层中注液或者抽液，卵石地层用于作为建筑结构的地基。该减震系统，能够通过向封闭卵石地层抽注液体改变卵石地层的质量，实现卵石地层惯性力大小的调整和自振频率的调节，通过卵石地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，还可避免天然卵石地基地震作用下砂土液化现象；能够直接利用天然卵石地层特性，实现调谐液体阻尼器减隔震效果的装置，且适用于不同地基条件，施工方便，同时耗能效果良好，该减隔震系统具有开创性的工程意义和实用价值。
