摘要:
以某化工园区的基础不均匀沉降地段的架空管道系统作为研究对象,该管道系统有10组立柱,4层桁架及27根管道,输送不同温度和压力工况的流动介质.采用自动安平水准仪测量架空管道立柱的沉降值,在此基础上考虑重力、介质温度、流动载荷等因素,系统完整地建立ANSYS有限元模型并进行数值计算,得到了不均匀沉降架空管道系统的位移、应力等参数分布.对2次应力进行了校核验算,以判断不均匀沉降地段的架空管道系统的可靠性,并估算出各个立柱的临界沉降值.旨在探索一套针对不均匀沉降架空管道系统实际应用的安全风险评估方法,为架空管道的安全运行提供坚实的技术支持.
Abstract:
In this study,the overhead pipeline system in the uneven settlement area of a chemical industry park is taken as the research object.The pipeline system consists of 10 sets of columns,4 layers of pipe racks and 27 pipelines,which transports the flow media under different temperature and pressure conditions.On the basis of measuring the settlement of overhead pipeline pillars with automatic level,considering factors such as gravity,medium temperature and flow load,the ANSYS finite element model is established sophisticatedly to perform the thermal fluid-solid coupling calculation.The displacement and stress distribution of overhead pipeline system with uneven settlement are obtained.The secondary stress is checked in order to judge the reliability of the overhead pipeline system and estimate the critical settlement of each column.The study aims to explore a set of safety risk assessment method for the application of overhead pipeline system with uneven settlement,and provide solid technical support for the safety operation of overhead pipelines.
