Abstract: Based on the analysis results from the geological disaster on gas pipeline and referencing the risk evaluation method of geological disaster, the earthquake risk elements are divided into five aspects, that is, disaster background, activity of the hazard-affected bodies, the feature of the affected objects, damage loss and prevention work. The researchers perform relatively comprehensive consideration and analysis of factors that may cause pipeline failure and establish a relative sound indicator evaluation for failure consequence, and detail some indicators according to the main types of pipeline earthquake disasters, and also determine the division of destruction level of earthquake to buried pipelines and corresponding failure probability range based on the analysis of earthquake disaster rate, and realize the failure risk level evaluation of gas pipelines in earthquake areas based on risk matrix method. This method can realize a general assessment of long-distance gas pipelines in an earthquake area.
