地铁站施工对邻近文物建筑的影响研究

地铁站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,一直受到人们关注。结合陈家祠地铁站工程实例,运用有限元法模拟基坑开挖过程的工况,分析基坑开挖对国家级文物建筑-陈家祠堂的影响,并采取有效措施,使邻近文物建筑站在基坑开挖及地铁运营时能确保安全。

Study on Influence of Metro Station Construction on Adjacent Historical and Cultural Relics Building

The metro station foundation pit excavation may cause uneven settlement and cause inclination and crack of surrounding underground structures, which has been highly concerned by the public. Combined with engineering example of Chens’Ancestral Temple metro station, the finite element method was adopted to simulate the working condition of foundation pit excavation and analyze the influence of foundation pit excavation on national level historical and cultural relics building-Chens’Ancestral Temple. Effective measures were taken to ensure the safety of metro stations of adjacent historical and cultural relics buildings in the foundation pit excavation and subway operation.
