Stratum environmental damage induced by urban tunnel construction is almost inevitable, which makes structures, roads and underground pipelines work improperly. This paper described the formula and details of development of a computer system. A prediction and control system for environmental damage induced by tunnel construction, named STEAD-RISK, was developed and introduced in this paper. This system had been developed in Delphi programming environment, by classical predict formulations, numerical analysis and three-dimensional imagery technology, prediction results and engineering field data was saved in database of this system, and then transfer was changed to visual three-dimensional maps. The main emphasis in this study was placed in developing calculation method and conversion between database from the system and points on the map. A newly computing package was developed in this program, which could predict settlement in construction site. By three-dimensional simulation, this code could transform predicted and monitored data into visual three-dimensional maps, in which the influence caused by construction to the stratum environment could be simulated veritably, so it's helpful for damage predictions and safe precautions. Finally, the paper presents a case application of the new system (Chinese version) in Beijing subway project.
