从研究腐蚀角度来看,钢桩式构筑物在海洋环境中的腐蚀一般被划分为五个区带,即海洋大气区、浪花飞溅区、潮差区、海水全浸区和海底泥土区。为减轻其腐蚀,必须对不同部位采取相应的防腐蚀措施。在海洋大气区和海水全浸区目前所采用的保护方法,可得到满意的保护效果。潮差区平均中潮位以下的部位,可以得到同全浸区基本相同的阴极保护效果,不须采取其他特殊的防腐蚀措施。而浪花飞溅区和潮差区平均中潮位以上部位腐蚀最为严重,采取防腐蚀措施也比较困难。为此,不少学者特别对浪溅区、潮差区的防腐蚀方法
From the perspective of corrosion study, the corrosion of steel pile structures in the marine environment is generally divided into five zones: marine atmosphere, spray splash zone, tidal range, seawater immersion zone and seabed soil zone. In order to reduce its corrosion, we must take appropriate anti-corrosion measures for different parts. The current protection methods used in the oceanic atmosphere and the seawater immersion area provide satisfactory protection. The tidal range below the average mid-tide position can be obtained with the same all-immersion zone of the same cathodic protection, without the need to take other special anti-corrosion measures. The spray splash zone and the tidal range of the average tide above the parts of the most serious corrosion, anti-corrosion measures taken more difficult. To this end, many scholars especially wave splash zone, tidal area corrosion method
