白马河特大桥主桥的防腐措施

Anticorrosion Measures for Main Spans of Baimahe River Bridge

白马河特大桥位于闽东沿海地区,主跨为(80+145+145+80)m双线连续刚构,其耐久性受海水腐蚀环境影响。通过对海工结构物遭受腐蚀调查及原因分析,从设计角度对影响该桥耐久性的因素进行分析,并提出相应的措施。

Located at the coastal area in the east of Fujian, Baimahe River Bridge is a doubletrack concrete continuous rigidframe bridge with main spans arranged as (80+145+145+80) m, and its durability is subjected to seawater corrosion influences. Through investigation of the corrosion and analysis of the causes of the corrosion of the structures in sea, the factors that may cause adverse influences on the Bridge durability are pointed out and corresponding measures against the corrosion are proposed from the angle of design.
