Application of Support Axial Force Servo System in Subway Deep Foundation Pit Engineering |
| |
| Abstract: | A set of self-developed support axial force servo system is introduced in this paper. It can take the displacement of retaining structures as the main control index and be able to control the steel support axial force in real time according to the structural deformation. The system has been successfully applied to a number of deep foundation pit projects in Shanghai. The field data detection results show that the system can effectively control the deformation of the foundation pit and improve the safety of foundation pit excavation. |
