摘要
基于AnsysWorkbench有限元分析软件,利用稳态热和静力学模块对冻土区埋地管道及其周围土壤温度场进行分析。分析发现:管道应力主要集中在弯头处,且埋地处的弯头应力较大;位移量则是在管道出土后的最前端出现最大值;土壤的温度场受低温管道的影响,在管道的四周形成了一个低温区,且温度以逐渐递增的形式向四周扩散。
Based on ANSYS Workbench finite element analysis software,the steady-state thermal and static modules are used to analyze the temperature field of buried pipeline and its surrounding soil in frozen soil area.It is found that the stress of pipeline is mainly concentrated at the elbow,and the elbow stress at the buried part is large;The displacement is the maximum value at the front end of the pipeline after excavation;The soil temperature field is affected by the low-temperature pipeline,forming a lowtemper ature zone around the pipeline,and the temperature diffuses around in the form of gradual increase.
