| Abstract: | Displacement and deformation of deep pit supporting system concern not only security of the pit, but also the safety of the surrounding environment. A security early warning system of supporting structure is set up.Based on the analysis of project design and construction surveying materials, an improved BP neural network is applied to establish a forecasting model of the displacement of deep pit supporting structure, some discussions on the surveying and early warning targets about it are studied. |
