摘要
摘 要:通过对国内外的文献分析与研究,介绍了PCCP数值计算方法的最新进展情况,阐述了国内外学者在PCCP管道数值分析研究中的研究内容和采用的建模方法,分析了不同建模方法的优缺点,并对现在建模所采用的预应力施加方法进行了对比。结合管道数值计算的研究动态,提出了管道数值计算研究的重点和需要进一步研究的问题。
Abstract:PCCP has developed dozens of years at home and abroad. It is necessary to carry out further research in the aspects of its stress model, experimental research, numerical analysis and structural reliability analysis. The numerical analysis is the main method of current research on pipeline structure performance. The PCCP calculation problems are introduced, the research contents and modeling methods that the domestic and foreign researchers involved in PCCP numerical analysis are mainly elaborated, the advantages and shortcomings of different modeling methods are analyzed and methods of prestressed steel wire of simulation are compared. Combined with foreign research direction, the direction of our country in PCCP numerical analysis are forecasted, the reference for pipes in numerical calculation are provided.
