摘要: 介绍了海底管线设计行业悬跨分析方法和判定准则从20世纪80年代起步到现在的最新发展,并通过算例按照不同标准分别进行海底管线最大允许悬跨长度计算,比较不同标准、不同方法在判定准则上的区别以及控制工况的新变化。分析了产生这些区别的原因,进而结合海管设计和在役评估工程经验,尤其是悬跨评估新标准在海管在役评估中的应用和成效,为今后的悬跨分析标准选用给出建议。

Abstract: The development trends of free spanning evaluation and related criteria in the pipeline industry from the 1980s are presented. An example is given to calculate the maximum allowable span length by different codes. Then, the differences in the criteria and critical cases are compared and the reasons for these differences are analyzed. Finally, based on the engineering experience and the in-service evaluation results, suggestions on the code selection for submarine pipeline design and in-service evaluation are given.
