摘　　要：通过对高桩码头生命全过程的分析,给出了码头混凝土构件抗氯离子侵蚀的耐久寿命的定义;在国内外研究成果的基础上,确定了普通硅酸盐水泥制成构件氯离子浓度临界值;根据氯离子扩散理论,建立梁板式高桩码头主要构件剩余使用寿命的预测模型,并通过具体实例证明了该模型的有效性。This paper gives a definition of high-piled wharf＇s residual life intruded by chloride ions through an analysis on its whole process.Critical value of chloride ions in components is made sure based on the research at home and abroad.According to the theory of chloride ions＇intrusion,we establish a prediction model of residual life about main components of high-piled wharf,and verify the effectiveness of the model by a practical example.
