摘　　要：在青岛海区以及渤海南部的埕岛海区进行了A3钢、16Mn钢、2 0 #钢及Z向钢的实海滩涂埋片实验、埕岛海区的海泥属于砂质泥类型 ,青岛海区为海沙、埋片方式分为单独埋片和电连接埋片两种方式 ,三年的实验结果表明 :对同一种钢材而言 ,海沙中的腐蚀速度高于海泥中的腐蚀速度 ;单独埋片的腐蚀速度高于电连接埋片的腐蚀速度 ,但两者相差不大 ;钢材短期实验的腐蚀速度要高于长期实验中的腐蚀速度 。Corrosion experiments of A 3, 16Mn, 20 # as well as ZCE36_225 steel were carried out in southern Bohai sea and Qingdao sea areas. The sea_bottom mud in southern Bohai sea area is the sandy mud and that in Qingdao sea area is pure beach sand. In this experiment, the compareing test of two modes with electric connected and non_electric connected modes was carried out. The experiment results showed that: 1) the corrosion rate of steel in sea_bottom mud has a strong relation with mud types. The corrosion rates of steels in pure beach sand are much higher than those in sandy mud. 2) The corrosion rates of non_electric connected mode are hingher than those of electric connected modes.
