摘要
为研究基坑施工和结构底板施工等对下方既有地铁隧道结构安全的影响,以某地铁上盖建筑为研究背景,运用有限元软件建立了地铁上盖建筑-地铁隧道的数值分析模型,分析了上部结构底板施工对下方地铁隧道变形的影响。并结合隧道变形的监测数据,探究了建筑结构底板施工对隧道变形影响的原因及控制方法。相关研究成果可为地铁上盖建筑的安全施工提供参考和依据。
To study the influence of foundation pit construction and structural floor construction on the structural safety of existing subway tunnels below,a numerical analysis model of subway superstructure-subway tunnels is established by finite element software,and the influence of the construction of superstructure floor on the deformation of subway tunnels below is analyzed.Based on the monitoring data of tunnel deformation,the causes and control methods of the influence of building structural floor construction on tunnel deformation are explored.The relevant research results can provide reference and basis for safe construction of subway superstructure.
