基于风险分析的某跨越管道泄漏计算

Based on the Risk Analysis of a Span Pipeline Leakage Calculation

长输管道输送的一般是高压力的易燃易爆物质,一般要求埋地敷设,但是对于一些特殊的地形,管道跨越在长输管道中亦常见。管道跨越由于暴露于地面上,更容易成为被破坏的目标,因而其安全备受关注。管道跨越往往位于地势险要之地,对于大跨度的跨越结构,悬索形式以其跨越能力大,设计、施工成熟而成为长输管道大跨度跨越的主要形式。对于管道跨越的专项环境影响风险分析,目前国内外还没有成熟的分析方法和分析报告。论文选取了一座跨度360m的油气双管同桥悬索跨越作为研究对象,为了分析跨越结构中的油管道泄漏后对跨越处的环境影响,对泄漏量的计算做一分析,供各位同行参考。

Long distance pipeline transportation is generally high pressure of flammable and explosive substances.General requirements for laying.Dut for some special terrain,pipeline bridge in long-distance pipeline is also common.Pipeline span due to exposure to the ground,to become more easily destroys the target,so the safety concern.Pipeline span is often located in the difficult terrain,to large spanbridge,suspension form across its large capacity,design,construction of long distance pipeline mature and become the main form of large span.For pipeline special environmental impact risk analysis,at home and abroad have not yet mature analysis method and analysis report This paper selects a span of 360 m oil and gas two-pipe bridge suspension spans as the research object,in order to analyze the span structure in the oil pipeline leakage on environment influence across,on the calculation ofleakage analysis,for your reference.
