Abstract: This paper demonstrates informational construction technology. During the process of constructing, the combination of data and the circumstances of the excavation engineering is synthetically analyzed, experimental data are made used of to produce feedback design and analysis, and these are of practical and theoretical sinnificance in the following work. The monitor during the working process of some deep excavation construction is introduced, and the importance of information construction is indicated. According to analysis on the data, information conclusion, and experience summary during information construction, there is a reference to similar projects.
