复杂地层盾构下穿敏感建筑群沉降控制研究

Research on the Settlement Control of Shield Tunneling Through Sensitive Complexes in Complex Strata

随着城市化进程的加速,地铁作为一种便捷的交通工具得到广泛应用,其建设过程中所带来的影响也愈发凸显。地铁隧道建设对周边环境和敏感建筑群体的影响是一个不容忽视的问题。以复杂地质条件下地铁盾构隧道施工过程中敏感建筑群的沉降控制为研究对象,通过综合运用理论分析和数值模拟的方法,探讨了沉降控制的主要影响因素和优化方法,提出了有效的控制措施,为地铁隧道建设提供了一定的参考。

With the acceleration of urbanization,a subway has been widely used as a convenient means of trans⁃portation,and the impact of its construction process has become increasingly prominent.The impact of subway tunnel construction on the surrounding environment and sensitive building groups is an issue that cannot be ignored.This paper takes the settlement control of sensitive building groups during the construction of subway shield tunnels under complex geological conditions as the research object,through the comprehensive use of theoretical analysis and numerical simulation methods,this paper explores the main influencing factors and optimization methods of settlement control,and proposes effective control measures,which provides a certain reference for subway tunnel construction.
