近年来海洋工程向大型、跨海、外海化发展,混凝土结构使用年限达到50a以上的目标已成为目前基本建设的迫切任务。由于混凝土耐久性的影响因素复杂,设计时往往难以把握具体的耐久性指标。文章中介绍了几种国内外用于评定海港工程混凝土耐久性的测试方法,结合中港集团建筑材料重点实验室近些年来对海港工程混凝土耐久性的研究和暴露实验研究成果,通过分析、比较,探讨海港工程混凝土结构合适的耐久性技术指标及寿命预测方法。

In recent years,marine works tend to become large,cross seas and extend offshore.To make concrete structures attain a service life of more than 50 years has become an exigent task in capital construction.As the factors affecting the durability of concrete are complex,it is often difficult to grasp the durability indicators during the designs.The paper presents an introduction to a number of testing methods for evaluating the durability of concrete for seaport engineering works and,in the light of the results of the researches and exposure tests on the durability of concrete for seaport engineering works made by CHEC-Key Laboratory of Construction Materials,makes a study of the rational technical indicators for the durability of concrete for marine works and the methods to predict the service life of the concrete by way of analyses and comparisons.
