摘要
滨海盐雾区环境因素复杂,对混凝土内部微环境有较大的影响。通过在滨海盐雾区实地设置环境观测站,得到了滨海盐雾区一年的环境资料,研究表明,深圳市滨海盐雾高温高湿的气候特征明显,1~12月份观测区域温度最高为37.9℃,全年湿度的变化区间为50%~89%,靠近海岸线位置的湿度较高;随着距海岸线距离的增加,大气氯离子含量迅速降低。
The coastal salt spray area has complex environmental factors and many corrosion sources,which puts higher requirements on the durability of concrete structures.Through the establishment of an environmental observation station in the coastal salt spray area,the environmental data of the coastal salt spray area was obtained for one year.The research shows that the high temperature and high humidity of coastal salt spray in Shenzhen has obvious climate characteristics.Meanwhile,the highest temperature in the observation area from January to December is at 37.9℃with the annual humidity range from 50%to 89%,and the humidity near the coastline is higher.As the distance from the coastline increases,the atmospheric chloride ion content decreases rapidly.
