摘要
临近地铁深基坑施工必然会影响周边隧道安全和使用,因此,有关人员在施工前采用有限元模拟分析其影响。本文结合某基坑施工工程,进行有限元模拟,探讨施工对附近隧道的影响,并与隧道监测数据进行对比分析,从而验证该有限元模型的适用性,为下续基坑工程施工前进行的有限元模拟提供依据,并结合监测数据和模型分析结果,给出一些初步结论和相关建议。
The construction of deep foundation pit adjacent to metro tunnels will inevitably affect the safety and practicality of adjacent metro tunnels, therefore, the finite element simulation analysis is used to analyze the influence. In this paper, according to the engineering practice of the construction of a Foundation Pit, the influence of construction of the foundation pit on nearby tunnels is simulated by fi- nite element method. To verify the applicability of the finite element model, the data for the analytic re- sults was compared with the monitoring data of the adjacent metro tunnels. And the analytic result can provide precondition for the finite element simulation of the construction of the next foundation pit, and combined with the monitoring data and model analysis results, some preliminary conclusions and related recommendations was given at the end of this paper.
