Test of Deformation of Protection Work for Foundation Pit by Cement Soil Mixing Pile Plus An-chor Bolts |
| |
| Abstract: | Cement soil mixing pile plus anchor bolts is a new supporting technology for foundation pit. Deformation data (lateral displacement and settlement) is obtained through site testing, and the characteristics of deformation of this structure are studied based on comprehensive analysis. An analysis and prediction is made of safe conditions of supporting structure during excavation of foundation pit, and the issue of alarming value determination is discussed. |
