Abstract: The establishment of informatization management system is helpful for the fast response and real time managing the safety related risks during the excavation of a large foundation pit. This paper presents a typical deep excavation project in Wuhan, which was closed to a subway tunnel and surrounded by densely distributed high-rise buildings. An information based and visualized construction management system for the deep excavation was established to assist the real-time early safety warning and emergency response. Through this system, the dynamic feedback analysis and the construction optimization of the large deep excavation stability can be realized by integrating the geological survey, design, construction, safety monitoring, and project management. Thereafter, it forms a complete set of technologies for information-based and visualized construction management of large deep excavation project. The results can provide a reference for the design and construction of similar deep excavations.

Key words: deep excavations, construction management system, information-based construction, visualized management system
