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.

在美国，加拿大，英国和其他具有先进管道管理的国家/地区中，一些组织负责地下有害物质的管道安全保护管理。危险材料管道的安全和维护是城市安全的重要考虑因素，因为地下管道运输的材料包含危险物品，例如固体，液体和气体的易燃或易爆颗粒。外力对管道的损坏通常会导致继发性灾难，例如有害物质的泄漏，火灾，爆炸和环境污染。这些事件严重影响了个人及其财产的安全。

因此，本研究使用带有空间网格的地震情景分析来评估地震对市区地下管线的破坏。对地下管道的损害进行了分类，讨论了管道灾害管理程序，并提出了改善措施，例如建立地理信息平台和对有害物质管道进行灾害影响评估。在包括地震在内的情况下对地下有害物质管道进行了评估。此类评估旨在提供减灾计划和防灾演习，以提高管道安全性，并提供用于抗震的管道材料计划。
