RESEARCH ON MESH DATA DIAGNOSIS MODEL FOR SAFETY EVALUATION OF WATER PIPELINE SYSTEM

Abstract

In our paper reported last year, we showed the accident risk assessment model and the leakage risk assessment model using the quantification theory for pipeline networks replacement planning. It became clear that diagnoses by the proposed models were helpful in identifying which parts shall be given priority attention. The purpose of this study is to verify the proposed risk assessment model using the data of another area. As a result of the case study for S city, it was revealed that our created model had a common frame as to model structure. Comparing the new model with the former one, it was suggested that suitable adjustments of the model were needed when we clearly defined a high-risk part in the target area.
