摘要
文章系交通运输部西部交通建设科技项目课题"海港工程混凝土结构耐久性寿命预测与健康诊断研究"部分成果。利用国内典型海洋环境长达20a暴露试验和实体海港工程耐久性调查成果,通过综合统计分析,对海工混凝土耐久性劣化模型关键参数进行合理修正,建立与我国典型海工混凝土结构相吻合的寿命预测模型,并采用对暴露试验"室内复原"的方法研究耐久性室内快速模拟试验与暴露试验之间的相关性,建立海工混凝土耐久性质量性能与设计使用年限之间定量关系。
Some research results of one Western transportation construction project named "Service Life Prediction and Health Monitor of Marine concrete structures" which is funded by Ministry of Transport are introduced in this paper. In the paper the key parameters of degradation model of marine concrete are modified rationally through statistical analysis to data obtained from long-~~,-m exposure test (20 years) and field investigation carried out in typical coastal areas of China, and then the service life prediction model that is suitable for the marine concrete of Chinese occasion is established. Through " recovery test" of exposure test, the relationship between indoor test and exposure test for concrete durability is studied and then the quantitative relation between durability performance and design life of marine concrete structures is established.
