摘要
建立有限元模型,对埋地压力管道带压开孔及实际运行两种工况进行有限元分析。对主管两端施加5种约束,分别进行管道应力的分析,比较开孔位置的应力分布情况,为类似工程管理提供借鉴。
Building the finite element modle,to carrie out finite element analysis which bury land pressure pipeline starting a hole with two kinds of work condition. Five of the constraints imposed in charge at both ends, with respectively pipe stress analysis, to compare the bore position of the stress distribution, provide instruction and draw lessons for this kind of engineering management.
