Evaluation Research on Influence of Subway Operation Vibration on Adjacent Buried Oil and Gas Pipelines
With the development of urbanization,it is difficult to avoid the crossing and accompanying between urban subway and buried oil and gas pipeline.In order to scientifically evaluate the impact of subway operation vibration on the adjacent buried oil and gas pipelines,based on vibration monitoring data of a subway line in Guangzhou,according to the characteristics of high strength and toughness of oil and gas pipelines and considering the fatigue life of oil and gas pipelines under micro vibration,the mechanical calculation and evaluation of pipelines under vibration load were carried out using strain-based mechanical criteria.The calculation results show that the vibration produced by the subway train has little influence on the safety of buried pipelines.It is suggested to establish an intelligent mechanical monitoring and early warning system for pipelines under the action of vibration load in subway operation to strengthen the tracking of the integrity state of oil and gas pipelines.
