| 摘 要： | 为保证既有地铁车站的正常运营和结构安全,在紧邻的基坑开挖过程中需要严格控制车站结构的变形。围绕对紧邻已有地铁车站侧边进行大面积地下空间基坑开挖的数值模拟及现场实测结果分析,提出了合理的设计方案及技术措施,为今后类似工程问题的设计及施工提供参考性建议。

| Abstract: | To keep the normal operation of existed metro station and to guarantee the security of station structure,the structure deformation of metro station caused by adjacent foundation pit excavation construction should be controlled strictly.Based on the numerical simulation and analysis of field monitored data around the big area underground space foundation pit excavation closing to existed metro station side,the optimum design plan and reasonable construction techniques are proposed,which can provide suggestions for the designs and constructions of similar projects in the future. |
