摘要
文章以中俄东线天然气管道工程(黑河—长岭段)中X80钢天然气管道参数为依据,基于国家相关压力容器安全评定规范,模拟分析了不同形状的落石撞击下,管道的应力和变形情况,对管道的设计和架空管道安全防护设施的设置具有指导意义。
Based on the parameters of X80 steel natural gas pipeline in China-Russia eastern route natural gas pipeline project(Heihe-Changling section),according to the national code of safety assessment for pressure vessels,the stress and deformation of the pipeline under the impact of falling rocks of different shapes are simulated and analyzed,It is of guiding significance to the design of pipeline and the installation of safety protection facilities of overhead pipeline.
