摘　　要：青岛一新建住宅楼位于青岛市胶州湾湾口海底隧道四川路接线端西侧,为了研究新建建筑施工对既有隧道产生的变形影响,文章基于MIDAS-GTS有限元程序构建建筑与隧道的三维有限元模型,从中揭示了隧道在建筑物不同施工阶段的变形响应。根据数值分析结果及相关工程经验,为以后建筑施工以及隧道维护,提供可靠的建议。A new residential building is located on the west side of Sichuan Road terminal of the undersea tunnel of Qingdao Jiaozhou Bay mouth, in order to stud- y the impact of the new building construction on the existing tunnel deformation, the three dimensional element models of buildings and tunnels were established based on the MIDAS-GTS finite element program,from which the tunnel deformation responses at the various construction stages of the building were revealed. According to the re- suits of numerical analysis and related engineering experience, reliable suggestions were provided for the future construction and tunnel maintenance.
