摘　　要：现场暴露试验是海工混凝土结构耐久性研究的一种重要手段,暴露试验所处劣化环境即为实际海洋环境,其试验结果真实且可靠。以试验站选址、试验的实施、试验数据的处理为主脉络,结合中外有关暴露试验的研究成果与进展,总结了现场暴露试验过程采用的方法。重点阐述暴露试验后所测氯离子浓度与各耐久性参数的关系,室内加速试验与室外暴露试验的相关性,以及目前暴露试验存在的问题与发展趋势,为今后开展现场暴露试验研究提供指导。Field exposure test is an important means to study the durability of marine concrete structures.The deterioration environment of exposure test is the actual marine environment,and its test results are true and reliable.Based on the site selection of test station,the implementation of test and the processing of test data,combined with the research results and progress of exposure test at home and abroad,the methods used in the process of field exposure test were summarized.The relationship between the measured chloride ion concentration and various durability parameters after the exposure test,the correlation between indoor accelerated test and outdoor exposure test,as well as the existing problems and development trend of the current exposure test were focused on,so as to provide guidance for the field exposure test research in the future.
