摘要
以上海市某砖木结构房屋为研究对象,对其受相邻地铁振动的影响进行实测,包括房屋振动响应及损伤实测。结果表明:地铁经过时,房屋各层楼板测点的铅垂向Z振级VLz的昼间和夜间评价量均小于《城市区域环境振动标准》(GB 10070—88)中有关"交通干线道路两侧昼间和夜间标准值"的规定限值;建筑物未出现明显的裂缝、倾斜、位移等损伤。该研究成果可为进一步研究地铁振动诱发建筑物的振动水平提供依据,为保障地铁沿线既有住宅安全使用及管理提供一定的技术参考。
Taking a brick-wood structure house in Shanghai as the research object,the effects of adjacent subway vibrations on the house are measured,including house's vibration response and damage measurement.The results show that when the subway passes,the vibration values of the vertical Z direction at all measurement points of each floor of the house are less than the"standard value limits for both sides of main traffic roads at daytime and nighttime"stipulated in"Environmental Vibration Standard for Urban Area"(GB 10070-88);buildings have no obvious cracks,tilts,displacements or other damages.The research results can provide a basis for the further study on the vibration level of buildings induced by subway vibration;and provide certain technical references to ensure the safe use and management of existing residential buildings along the subway.
