摘　　要：青岛港一期油码头的钢栈桥为三角形负管桁架结构,由于长期处于海洋环境中,结构腐蚀严重,安全状况不明。采用普查和重点检测相结合方法,查清主要构件外形尺寸与变形情况、锈蚀构件分布情况;选取具有代表性跨别作重点检测,进行脉动试验和结构应力测试;结合结构性态的有限元分析,得出了钢引桥结构腐蚀严重的结论,建议对腐蚀严重部位补强加固,结构整体实施防腐处理。Approch bridge of oil wharf in Qingdao port uses triangle trusses structure,and the numbers ware highly corroded in marine circumstance. To obtain the safety situation, general investigation and key-point inspection were adopted, the structural size, deformation, corrosion distribution were checked; and pulsating loading tests and stress measurement were carried out for typical sections. It was indicated that the corrosion of steel land stage was serious, it was necessary to reinforce the serious corroded numbers and the whole structure showld be treated for perservation.
