中文摘要:
      随着经济的发展,城市出现了大量的基坑工程,开挖基坑时会引起地表沉降和变形。当地表沉降达到一定程度会影响地面建筑物和地下管线的安全,所以必须严格控制因基坑开挖引起的地表沉降。本文基于合肥地铁2号线青阳站基坑的地表沉降监测数据,利用ORIGIN软件进行数据分析,并结合了数值模拟的结果,给出了基坑开挖对地表沉降影响的相关规律,为今后的类似工程提供借鉴。
英文摘要:
      With the development of economy, a large number of excavation works have appeared in city, and surface subsidence and deformation are caused by the excavation of foundation pit. When the surface subsidence reaches to a certain extent, it will affect the safety of the ground buildings and underground pipelines, therefore it is necessary to strictly control the surface subsidence caused by foundation. The paper has been based on the data of the surface subsidence monitoring which are from foundation pit of Qingyang station of Hefei Metro Line2, using ORIGIN software for data analysis, and combined with the results of numerical simulation, this paper provides the law of the foundation pit excavation on the ground surface settlement which provides reference for similar projects in the further.
