Disaster impact assessment of the underground hazardous materials pipeline

In the United States, Canada, the United Kingdom, and other countries with advanced pipeline management, some organizations are responsible for pipeline safety protection management for underground hazardous materials. The security and maintenance of a hazardous material pipeline are serious considerations for urban safety, because the materials transported by underground pipelines contain hazardous goods, such as the flammable or explosive particles of solids, liquids, and gases. Damage to a pipeline by external forces often leads to secondary disasters, such as the leakage of hazardous materials, fires, explosions, and environmental pollution. Such events seriously affect the safety of individuals and their property. Accordingly, this study used seismic scenario analysis with a spatial grid to evaluate earthquake damage to an underground pipeline in an urban area. Damage to underground pipelines was classified, pipeline disaster management procedures were discussed, and improvement measures were proposed, such as establishing a geographic information platform and conducting disaster impact assessments for hazardous material pipelines. Underground hazardous material pipelines were assessed in scenarios including earthquakes. Such assessments are intended to provide disaster reduction plans and disaster prevention drills to improve pipeline safety as well as the planning for pipeline materials to aid seismic resistance.

Automated summary

This study evaluated earthquake damage to underground pipelines in urban areas and discussed pipeline disaster management procedures and improvement measures, such as establishing a geographic information platform. These measures aim to enhance pipeline safety and reduce the likelihood of secondary disasters.
