Study on Old Building Protection in Deep Excavation in Complex Urban Area |
| |
| Abstract: | Relying on CCCC Shanghai Headquarters Base project, according to the structural characteristics of the historical building protected within the reach of engineering, a series of protection measures were proposed. Simulation analysis of the deformation of bulding foundation during pit excavation was carried out by use of midas GTS NX finite element software, and then the field monitoring data was compared. The calculation result and the practical verification show that the relevant technical measures can ensure the safety of foundation pit supporting structure and historical building. |
