青岛地铁隧道开挖引起的地表变形及其对上部建筑物的损伤研究的中期报告 摘要: 本研究旨在探讨青岛地铁隧道开挖引起的地表变形及其对上部建筑物的损伤情况。通过对青岛地铁1号线的一段隧道开挖工程进行监测,测量了隧道开挖前后地表的垂直位移和水平位移情况,并对邻近建筑物进行了承载力分析。结果显示,在隧道开挖过程中,地表发生垂直位移和水平位移,而且位移量随着距离隧道越远而逐渐减小。此外,建筑物的结构受到了一定程度的影响,但是未达到破坏的程度。 关键词:青岛地铁;隧道开挖;地表变形;建筑物损伤;承载力分析 中文论文题目:青岛地铁隧道开挖引起的地表变形及其对上部建筑物的损伤研究的中期报告 Introduction Theconstructionofurbanrailtransitcanbringgreatconveniencetopeople'stravel,butitwillinevitablycausesomeimpactonthesurroundingenvironmentandbuildings.Theexcavationofsubwaytunnelswillcausedeformationoftheground,whichwillaffectthesafetyofadjacentbuildings.Therefore,itisnecessarytostudythedeformationcharacteristicsofthegroundcausedbysubwaytunnelexcavationandthedamagetoadjacentbuildings.
