管道运输成为与航天、铁路、公路、水路等并驾齐驱的五大运输方式之一.但是随着管道服役年限的增加以及由于加工制造等方面的问题,管道不可避免的存在这样或者那样的缺陷,影响管道的使用寿命.管线可靠性分析是管道完整性评价的主要内容之一.管道的爆破压力作为评价剩余强度的一部分,一直是国内外专家、学者研究的重要内容.爆破失效理论认为即使管道达到整体屈服,全部塑性,也不能认为就已失效,只有当压力增大到某一定值时,由于变形加大,使壁厚减薄,承载能力降低,管道才发生爆破.
本文首先对含缺陷埋地管道进行了缺陷简化模型,根据数据确定了计算公式,计算得出了该条件下的爆破压力.并通过ANSYS有限元软件进行了模拟仿真.
之后改变缺陷深度和缺陷长度的数值,应用ANSYS进行仿真计算,得出了爆破压力分别与管道缺陷深度和缺陷长度的关系,并对其进行了归纳总结.
最后,基于老龄管道的各种失效模式,开展老龄管道腐蚀的可靠性分析,系统的研究了缺陷初始深度d等七个参数对老龄管道系统可靠性(即失效概率)的影响及其敏感性分析；提出一种基于Monte-Carlo的老龄管道失效概率评估模型.

Pipeline transportation into and aerospace, railways, highways and waterways to keep pace with one of the five modes of transport. But with the pipeline as a result of the increase in service life and other aspects of the processing pipeline, or as the inevitable existence of such defects affect the service life of pipeline. Pipeline Pipeline Integrity Assessment of reliability analysis is one of the main contents. Pipeline burst pressure as part of evaluation of residual strength has always been foreign experts, scholars, an important part of the study. Even if a piped burst failure theory achieve the overall yield, all plastic, has been failure can not be considered only when the pressure increases to a certain value, as deformation increased, so that wall thinning, reduced carrying capacity, pipeline explosion occurred only .
This article first buried pipelines containing defects simplified model of the defect, according to data to determine the calculation formula, calculated under the condition of the bursting pressure. By ANSYS finite element software for simulation.
After the defect depth and defect length values, application of ANSYS simulation calculation, were obtained with the pipe burst pressure defect depth and defect length of relationship and their were summarized.
Finally, based on various failure modes of aging pipelines and carry out reliability analysis of aging pipeline corrosion, the system of initial defect depth d in seven parameters on the aging pipeline system reliability (ie failure probability) and its sensitivity analysis; proposed based on Monte-Carlo's aging pipeline failure probability evaluation model.
虽然我只是个初二的,但我的英语还不错,希望对你有所帮助,我也不能保证全部准确,只是差不多吧! 给分哈!
