| 摘 要： | 西南交通大学建成的8m×10m/160t振动台是目前国内规模最大的振动台,对其运行质量和振动影响进行评价具有示范效应。探讨该振动台振动影响的现场实验于2017年初展开,实测结果表明:该振动台在工作频段内受控性能很好,对地震动信号重现度很高;台面满载满负荷运行时实验室建筑基础10m以内地面振动加速度实测值不超过6.6gal,振动速度小于2mm/s,不会对实验室厂房及附属办公建筑的安全、使用舒适性及人们正常工作、生活造成不利影响。

| Abstract: | The free-field vibration induced by the 8m×10m/160t shake table was analyzed and measured. The shake table performs well with good frequency response and high reproducibility for strong ground motion signal. The induced free-field acceleration within 10m from the shake table foundation is only 6.6gal while the table runs at its full capacity,and the induced velocity is less than 2mm/s. Therefore,the full load operation of the shake table has no significant impact on human bodies and safety of buildings. |
