| 摘 要： | 以北京地铁7号线虎坊桥站暗挖出入口临近京华印书局为背景,运用有限元数值模拟软件MIDAS/GTS建立数值模型,分析出入口暗挖引起的地表及建筑物沉降量,确定合理的支护措施,根据隧道开挖过程中对应地表及临近建筑物的实际情况,优化开挖断面围岩预处理方案,并与实测沉降量进行拟合。模拟结果表明,采取相应加固措施后古建筑物沉降在安全范围内,可以为类似工程提供参考。

| Abstract: | This text, based on the underground excavation section of Beijing Subway Line 7 Jinghuayinshuju Press, employs the finite element numerical simulation software MIDAS/GTS to analyze the subsidence of surface and the building caused by underground excavation. Then supporting measure is determined and preparative treatment scheme of surrounding rock will be optimized on the basis of the actual situation during tunnel excavation, and the measured subsidence data will be matched. As a result of the simulation, the structure subsidence is within the scope of the security with corresponding strengthening measure, and this can be taken as reference for similar projects. |
