| Abstract: | 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. |
