天津地区深基坑开挖对历史建筑的影响分析

Influence on Historic Buildings Analysis of Deep/Excavation in Tianjin Region

随着城市化进程的推进,城市中历史建筑的保护日益受到重视。城市中修建深基坑工程,不可避免的会对周边历史建筑产生影响。结合天津地区深基坑工程实例,分析了历史建筑受深基坑开挖影响的破坏机理,认为基坑周边土体不均匀沉降是引起历史建筑破坏的重要原因。同时,根据监测结果,分析了天津地区历史建筑的变形规律,探讨了减小建筑物变形的措施,可为类似工程提供参考。

Along with the fast pace of urbanization, the protection of historic buildings draw lots of attention in the city. Deep soil excavation engineering in the city will inevitably affect the surrounding historic buildings. Combined with the Tianjin area deep excavation engineering examples, this paper analyzed the failure mechanism and considered uneven subsidence is an important reason. Also, according to the monitoring results, The author analyzed the deformation law in Tianjin region, and discussed the measures to decrease the building deformation. The results can provide a reference for other similar projects.
