Abstract
The purpose of this study (I) is to provide a new methodology for evaluating deterioration of buried pipe networks for the large-diameter old pipe improvement project currently performed by K-water. To develop a new assessment model for large-diameter pipe deterioration, this study has investigated the three representative methods for the pipe deterioration assessment such as evaluation methods 1995 and 2002, and the state evaluation method through literature reviews. The ten assessment factors were selected by considering large-diameter pipe characteristics as well as common factors with high priority in the three methods. Also, the weighting of the factors was estimated by a regression equation from experiments and analysis on domestic large-diameter pipelines and expert survey data. It is expected that the new assessment model developed by analysing the existing three models is more reliable to assess the deterioration of large-diameter pipe networks.
