摘　　要：以典型海洋环境干湿循环环境下氯盐侵蚀混凝土的现场试验为背景,分析沿海地区混凝土在干湿循环条件下氯离子侵蚀的参数;以潮差区环境区域为例,模拟现场环境参数,完成了室内加速模拟试验方案。对比研究了自然环境和室内试验数据结果,分析了主要侵蚀参数之间的相似性。On the basis ofonsite experiment of chloride ion penetration into concrete in typical marine environment under wetting-drying cycle, the ingress parameters of chloride ion penetration into concrete under wetting-drying cycle in littoral.For instance the environments of the tidal zone, the onsite environmental elements were simulated and the accelerated test program was completed.By comparing the results from the indoor acceler- ated test and the onsite test investigation,the similarity of the main ingress parameters between the indoor and onsite durability tests were analyzed.
