摘　　要：采用解析法研究穿越地表建筑物浅埋隧道开挖对地表沉降的影响,推导出了穿越地表建筑物浅埋隧道施工引起的地表沉降公式,依托广州地铁五号线右线区庄区间隧道穿越地表建筑物工程实例,验证了此方法的可行性,可为类似穿越已有建筑物隧道工程提供一定指导。This paper studies impacts of shallow-buried tunnel excavation throughout ground buildings on ground settlement uses analysis method, and induces the ground settlement formula caused by shallow-buried tunnel excavation throughout ground buildings. Based on Guangzhou subway No. 5 line right line sectional tunnel across ground buildings engineering, it testifies its feasibility, which can provide certain guidance for existing buildings tunneling engineering.
