天津奈伦国贸大厦深基坑支护工程变形监测研究

Research on Deep Excavation Support Deformation Monitoring for Tianjin Nairn International Trade Building

天津奈伦国贸大厦基坑属于深基坑工程,开挖深度和面积均较大。本文详细介绍了该基坑支护工程的监测方案,并从基坑底部隆起变形、基坑外围水位变化以及支护结构水平位移变化值进行分析。目前的监测结果表明,该基坑支护较为安全可靠,但基坑外围的水位变化情况需引起重视。

Deep Excavation of Nairn International Trade Building in Tianjin is a deep foundation pit, excavation depth and area were large. This paper mainly introduces the monitoring program of the deep excavation side slope support project. The pit bottom of the uplift deformation, water level change and monitoring results show that the excavation is comparatively safe and reliable, but the water level change in the external foundation needs paying attention.
