摘要

This paper mainly analyses the one-off repairing problem of the servicing components of the well structure. The function of the well engineering structure may degenerate over time during it service so that the life of the well may be affected. According to the inspected data, the attenuation law of the resistance can be given, and the time-variant reliability index of component can be calculated. On the basis of the reliability and cost-effective criterion, the remaining service life of existing well engineering structure can be given, and net benefit expectations can be given on account of repairing in random time. Finally, the optimum of repairing time point is determined for existing well engineering structure.
