摘要
In order to study the damage patterns of natural gas and water pipelines in the Ji-Ji earthquake, a GIS database and analysis procedures were established. Repair statistics was obtained from major natural gas companies and the Taiwan Water Supply Corporation (TWSC), and entered into the system. Then, repair fates (RR) were calculated. Previously, damage was analyzed without considering the corresponding pipeline material and diameters. In this study, new attempts were made to collect more data including those related to the composition of pipelines to provide-a more detailed analysis of the relationship between earthquake forces and the resulting damage. Statistical analysis Was also conducted to understand the correlation between RR and seismic parameters such as, the peak ground acceleration, peak ground velocity, and spectrum intensity.
