| 摘 要： | 选取重载铁路沿线四处有代表性的单层砖混结构建筑物为研究对象,建筑物中心距离铁路分别为6.5 m、15 m、26 m、38 m,其中15 m处的建筑物可作为铁路振动引起建筑物损伤的典型样本。对由列车引发的建筑物基础和屋顶处的振动响应进行现场测试和分析,并将峰值振动速度PPV实测结果与中外相关标准进行对比。结果表明,当峰值振动速度PPV超出GB 50868-2013中的第三类振动限值时,会对我国铁路沿线"建造质量较差的建筑"产生损害。

| Abstract: | This paper selects four representative residential buildings along the railway as research objects, all of which are of one layer brick-concrete structure, and the distances are 6.5m, 15m, 26m and 38m respectively away from the railway, where 15m buildings’ damage can be used as typical samples. Field test and analysis are conducted on the foundations and roofs’ vibration, at the same time, comparing the PPV results measured data with Chinese and foreign related standards. Results showed that, when the PPV is greater than the third class vibration limits in GB 50868-2013, the poor quality buildings along railways of our country will damage. |
