| 摘 要： | 对近年来考虑腐蚀影响的船舶结构可靠性计算各主要研究层面的研究现状做了介绍与评述.通过这一综述可以发现:此领域研究工作重心已由考虑线性、非线性均匀腐蚀的影响逐步向局部腐蚀尤其是点腐蚀方向转变.今后的研究重点为以下三个方面,即:①发展符合基本腐蚀机理、与实测腐蚀数据较为吻合的点腐蚀多指标模型;②确定蚀点几何参数在各类荷载条件下对构件强度的影响;③深入评估腐蚀与疲劳的相互作用对结构可靠性计算的影响.

| Abstract: | The reliability analysis of ship structures considering corrosion in recent years is reviewed.By this summarization,it is found that the emphasis of this research field have converted from general corrosion to localized corrosion,especially,the pitting corrosion.The important aims of the future work may be as follows:first,developing the new pitting corrosion model which will be more precisely to predict the statistical characteristics of corrosion wastage of ship structures;next,studying the ultimate strength of corroded structural components under various loads,to find out the main influencing geometry parameters of pit;third,evaluating the reliability of ship structures considering the interaction between corrosion and fatigue. |
