广州大学城某学生宿舍楼环境振动实测与分析

Environmental vibration measurement and analysis of a dormitory building in Guangzhou Higher Education Mega Center

结合广州大学城某一学生宿舍楼,通过现场实测和问卷的方法,对建筑物振动进行了分析研究。结果表明,28.6%的竖向振动实测结果超过《GB 10070—1988》规定的昼夜标准限值,人员流动数量和室内人员数量是宿舍楼竖向振动的重要影响因素;宿舍楼水平向振动的变化规律与竖向振动的变化规律较为相似,水平向等效振级整体上比竖向大,不论是水平向振动还是竖向振动,宿舍楼的顶层振动最强;问卷调查结果显示,短期内宿舍楼振动基本没有对居住人员的生活造成影响。

Combining with a seven-story dormitory building in Guangzhou Higher Education Mega Center,the vibration of the dormitory building was analyzed through field tests and questionnaires,The results showed that 28.6%of measurement data of the vertical vibration of the dormitory building exceeded the day and light limit values of GB10070—1988 standard,and the amount of the students stepping in and out and the amount of the indoor students were the important influencing factors for vertical vibration.The changes in the horizontal vibration of the building exhibited a similar trend with that in the vertical vibration of the building,the horizontal equivalent acceleration level was generally higher than the vertical equivalent acceleration level,and both the horizontal vibration and the vertical vibration were the greatest at the top of the building.The results of the actual survey and the questionnaire indicated that the vibration did not affect the students’lives of this building in the short term.
