| Abstract: | We made a system monitoring of retaining structure for deep excavation which mainly includes the force monitoring of soil nail＇s lacing wire, monitoring of anchor＇s axial force and horizontal displacement monitoring of slope top. According to analyzing the characteristics and correlation of the force of soil nail＇s lacing wire, anchor＇s axial force and horizontal displacement monitoring value of slope top and comparing it to the traditional mechanical model, the universality and particularity of the technical application of ultra-deep foundation pit were summarized, it will provide reference for other similar projects. |
