Abstract
The recent advance in mechanical and electronic technologies has been of great benefit and influence to civil engineering constructions which, starting at the planning, proceed in the order of designing, construction and maintenance. As further advanced, these technologies must be effectively used incorporated with suitable construction management technology.
In this direction, this paper presents the results of an introduction of reliability technology into construction management on a pressurized slurry shield tunnel construction in city, where unfavorable soil properties and water percolation often become great disadvantageous, and where trouble induced in the excavation machinery with oil pressure, and electronic equipments become critical cause to the construction time schedule.
