Benchmarking and difference analysis of risk control technology of geological disaster of mountain pipeline

Abstract

Pipelines in China's mountainous areas are widely distributed, running through the northwest to the southeast and the central, southwest, northeast and other regions, often inevitably passing through complex and steep mountainous areas. It is found that the common geological disasters in China's pipeline inspection include collapses, landslides, debris flows, water damage, etc. Due to the characteristics of high pressure, flammability and explosiveness, once a geological disaster occurs, it is easy to cause casualties, property losses and bad social impact. Therefore, it is of great significance to carry out research on the risk management and control technology of geological disasters in mountainous areas. Bibliometric and categorical statistics are used to analyze the differences between domestic and foreign risk management and control technologies and other linear engineering technologies such as pipelines and highways, railways, power grids and land. The risk management and control technologies studied include identification technology, risk assessment technology, monitoring and early warning technology, and prevention and control technology. By condensing the important technical characteristics of geological disasters of domestic and foreign linear engineering pipelines, and combining their advantages and disadvantages, the technologies worthy of reference for China's mountainous pipelines are summarized. These technologies can be used as scientific and reliable protection and control guidance for mountain pipeline engineering in China, and provide strong support for ensuring the safe operation of mountain pipelines.
