Abstract：With the development of informationization and requirement of the deep excavation，it is important to develop a strong information management system for the foundation pit engineering. Based on the analysis of the pre-existing foundation pit information system，a new digital foundation pit system was provided. And using the object-oriented language，database technique and 3D visualization technique，a digital foundation pit had been developed in this paper. Through this system，the engineering geological conditions of the engineering area，monitoring points and foundation structures could be queried and managed dynamically in 3D space. Also the monitoring data can be queried visually in sheet or curves，and according the previous monitoring data the developing trend in the future can be predicated conveniently. As an example，the system has been used in the excavation of the foundation pit of the Tianjin cultural centre. According to the analysis of the system，some results have been obtained on the deformation rules of the diaphragm retaining walls during the excavation process. According to the comparison between the predicting and the monitoring results，the prediction method in the system is well. The idea of the digital foundation pit system and the corresponding software developed in this paper，which is very useful for the development of the information construction of the deep excavation and other geotechnical engineering.
