摘要
以某大桥钢管桩牺牲阳极保护工程为例,介绍牺牲阳极保护系统保护电流密度的选取、牺牲阳极的选定及关键技术问题与处理措施,工程实施后测得钢管桩保护电位值均在设计保护电位范围之内,即-0.85^-1.10 V(相对于铜/饱和硫酸铜参比电极),钢管桩得到了有效保护。
Based on the sacrificial anode protection of steel-pipe piles of a bridge project,more detail was given for the selection of protective current density,determination of sacrificial anode,key technical problem and countermeasures. After the project was implemented,the detection data proved that the protective potentials of steel-pipe pile were in the design protective potential range from-0.85 to-1.10 V（relative to reference electrode of copper/saturated copper sulfate）. The steel-pipe piles were protected effectively.
