考虑点腐蚀影响的海洋钢结构剩余极限强度研究进展

为得到考虑点腐蚀影响的海洋钢结构剩余强度研究领域的发展趋势,本文对国内外该领域公开发表的文章进行综述,根据本文的研究可以发现:由于海洋钢结构的大尺度和复杂性,数值模拟已成为受蚀船体结构剩余强度的主要研究方法,但模拟结构的有效性仍需进一步检验;对于点腐蚀,就研究参数而言,长细比、DOP、体积损失是学者们最为关注的指标,但对点蚀板强度缺少时变可靠性研究;计算模型中都缺乏对焊接残余应力的考虑.本文所做的研究可为该领域下一步研究方向提供参考.

Review of marine structures residual ultimate strength considering pitting corrosion

To get the development trend of marine structures residual ultimate strength considering the influence of cor-rosion, the paper reviewed articles published in this field at home and abroad, according to the research of this paper:due to the large scale and complexity of marine structures, numerical simulation has become the main research method of the resid-ual strength of corroded marine structures, but the simulation validation still needs further inspection. In terms of corrosion parameters, slenderness ratio, DOP, volume loss were the most attention indexes for researchers, but there is a lack of time-dependent research. The calculation model is lack of considering welding residual stress. The review done in this paper can provide reference for further research in this field.
