| 摘 要： | 隧道开挖会对周围土体产生扰动,并伴随着土层变形。有时候变形过大,地表沉降引起塌方,会严重影响着施工质量和作业人员安全。基于此,结合某市地铁二号线8标工程实例,采用数值模拟的方法对不同间距隧道开挖地表沉降规律进行研究,能够为类似工程施工提供一定的参考和借鉴。

| Abstract: | Tunnel excavation will result in disturbances to the surrounding soil,often associated with soil deformation.Sometimes the soil deformation is too large,and landslides will be caused by surface subsidence,which has a serious impact on the quality of construction and safety of operating personnel.Given this,combined with No.8 standard engineering practice of Metro Line 2 in one city,this paper uses numerical simulation methods to study the law of the surface subsidence of tunnel excavation with different spacing.It can provide a certain reference for the construction of similar projects. |

| Keywords: | double line different spacing surface subsidence law |
