| 摘 要： | 基坑开挖引起地面不均匀沉降并导致周围地下构筑物倾斜、开裂等问题，一直以来受到人们关注。文中结合具体工程实例采用有限元法模拟基坑开挖过程的工况，分析基坑开挖对周围地铁隧道和地铁车站的影响，通过对比基坑开挖前后地铁车站和地铁隧道的位移和弯矩变化来判断基坑开挖和支护方式的合理性，提出相应的预防和保护措施，具有很重要的工程实际意义。

| Abstract: | Ground excavation caused by uneven settlement and lead to surrounding underground structure, tilting the problem such as craze, has been under concerned. Based on the specific engineering example using fem simulation excavation process conditions and analysis of foundation excavation of surrounding buildings impact, through comparing excavation around subway station and tunnel displacement variation and bending to judge the excavation and supporting the rationalities and corresponding preventive and protection measures have important engineering practical significance. |
