PCCP在运行过程中,由于制造、施工以及运行环境变化等诸多因素的影响,会出现不同程度的损伤,甚至发生爆管事故,严重影响供水管线的安全运行。为此,从PCCP的损伤成因和管线运行维护的基本需求出发,针对PCCP损伤成因、安全评估流程、获取风险指标和结构破坏概率等主要环节,收集、整理和分析了与PCCP损伤和评估相关的文献,介绍了现有用于PCCP安全评估的相关技术,并分析了这些评估技术的精度和相互关系,在总结破坏概率和破坏预测模型的基础上,讨论了PCCP安全评估未来的研究方向。结果表明,用于PCCP安全评估的技术和模型种类繁多且都具有一定的局限性,具体评估方案的选择应综合考虑破坏后果、检测精度和经济成本,以实现管线安全运行和投资收益最大化。
Abstract：During the operation of pre-stressed concrete cylinder pipe(PCCP), the damages of various degrees and even pipe-bursting accident are possibly to occur due to the impacts from a lot of factors, e.g. manufacture, construction, change of operation environment, etc., which can greatly impact the safety of the operation of the water supply pipeline. Therefore, the literatures related to the PCCP damages and the relevant assessments are collected, sorted out and analyzed for the key-links of the damage causations of PCCP, the safety assessment process, acquiring the risk index and structural failure probability, etc. from the aspects of the damage causations and the basic demand of the operation and maintenance of the pipeline, and then the relevant existing techniques for the safety assessment of PCCP are introduced, the accuracies of the assessment techniques and the correlations among them are analyzed, simultaneously, the failure probability and failure prediction models are summarized, while the future trend of the study on the safety assessment of PCCP is discussed as well. The study result shows that a great variety of the techniques and models are used for the PCCP safety assessment, but all of them have their limitations, and then the damage consequence, detection accuracy and economic cost must be comprehensively considered for the selection of the specific assessment scheme, so as to realize the safe operation of the pipeline and the maximization of the income from the investment.
