Abstract: As the urban buried gas pipeline is complex in structure, long in service life, and vulnerable to the impact of illegal occupation, corrosion, external damage and other factors, great security risk is brought about, which is a serious threat to the public safety of cities. The traditional technology for accident prevention and control of buried pipelines has been unable to meet the increasing demand for public safety. Hence, combining the accident prevention and control technology of pipeline with the cutting-edge information technology has become the current hot spot of research. Herein, the research status of accident prevention and control technology for the buried gas pipelines was summarized, the big data technology was applied to prevent and control the pipeline accidents (including the distribution of monitoring points, risk assessment, risk warning and emergency decision-making), and the challenges for application of big data technology in the accident prevention and control of pipelines and the resolutions were reviewed, so as to provide reference for the development of accident prevention and control technology of the buried pipelines in China to the direction of informatization and intelligentization.
