摘要
天津高银中央商务区一期基坑工程具有开挖深、面积大、设计施工难度大等特点。本文对该基坑内支撑支护体系的受力及变形特征进行了理论计算和实测数据对比分析,结果表明:两者的数据结果具有很好的一致性,说明该基坑内支撑体系受力合理、整体刚度强,能够有效地控制变形;同时也说明该基坑工程的设计与施工实现了很好的统一,使得该基坑工程能够安全、有效地得以实施。
The excavation pit of Goldin CBD project in Tianjin is deep, wide and very difficult in construction. The mechanism and deformation calculation of internal supporting system is performed, and the monitoring data is analysed. The calculation is consistent to the monitoring data, which is proved that the design of supporting system is reasonable and the integral rigidity is strong enough to control deformation effectively. Meanwhile it also shows the design and construction worked well ensured the excavation safely and effectively.
