使用20年岸壁式钢板桩码头的腐蚀与破坏

Corrosion and Failure of Steel Plate Piles of Quay Pier after Using Twenty Years

通过对钢板桩岸壁式码头钢筋混凝土胸墙破坏情况及水下钢板桩腐蚀程度的检测,码头胸墙多处因船舶撞击而破损,混凝土保护层严重剥落,钢筋腐蚀严重;水下钢板桩无大的变形和异位现象,钢板桩平均腐蚀速度为0.039 mm/a。

Through inspecting the parapet and steel plate piles of quay pier, the results show that many places of the parapet of pier dilapidate due to ships striking, concrete cover flake off and steel bar corrosion seriously,there is no large distortion and shift of steel plate piles below water,the mean corrosion rate of steel plate piles is 0. 039 mm/a.
