合肥地铁深基坑开挖对临近建筑物沉降的影响分析

Analysis on the Influence of the Building Settlement During Excavating at Hefei Subway Station

城市地铁建设常位于建筑物众多的城区,为避免影响周边建筑物的安全,必须严格控制因基坑开挖引起的建筑物沉降。本文通过对合肥地铁二号线潜山路站周边建筑物沉降量的监测值进行分析,并结合数据拟合的曲线,探讨了基坑开挖过程中建筑物沉降的一般规律,为以后的施工和将来的地铁建设提供指导和建议。

The construction of subway is often located in the urban area with dense buildings. In order to avoid affecting the safety of surrounding buildings, building settlement caused by excavating must be strictly controlled .Based on the building settlement data at Qianshan Road Station of No.2 subway in Hefei, this paper discussed the related rules of building settlement during excavating process through the analysis of the building settlement data by numerical fitting . The results may provide guidance and suggestions for the project and subway construction in the future.
