随着城市化的发展,城市地铁与油气埋地管道交叉伴行难以避免.为科学评价地铁运行振动对邻近埋地油气管道的影响,文中基于广州市某地铁线路运行振动监测相关数据,根据油气管道具有高强度、高韧性的特点,考虑了微振动条件下油气管道的疲劳寿命,采用应变为基础的力学准则对振动荷载下的管道进行力学计算与评价.计算结果表明地铁列车运行产生的振动对埋地管道安全影响较小.建议建立地铁运行振动荷载作用下管道智能力学监测预警系统,加强对油气管道完整性状态的跟踪.
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.
