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。
選取重載鐵路沿線四處有代錶性的單層磚混結構建築物為研究對象,建築物中心距離鐵路分彆為6.5 m、15 m、26 m、38 m,其中15 m處的建築物可作為鐵路振動引起建築物損傷的典型樣本。對由列車引髮的建築物基礎和屋頂處的振動響應進行現場測試和分析,併將峰值振動速度PPV實測結果與中外相關標準進行對比。結果錶明,噹峰值振動速度PPV超齣GB 50868-2013中的第三類振動限值時,會對我國鐵路沿線“建造質量較差的建築”產生損害。

Four representative residential buildings of single-layer brick-concrete structure with the distances of 6.5m, 15m, 26m and 38m respectively away from the railway were selected to study their damage situations. Of them the building 15m away from the railway was used as a typical sample of damage. Vibration responses of the foundations and roofs of the buildings induced by the train operation were measured and analyzed. The measured data of PPV of the vibration velocity was compared with that of domestic and international standards. Results show that, when the PPV of the vibration velocity exceeds the vibration limits of the third kind in GB 50868-2013 standard, the poor quality buildings beside the railway will damage.
