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。
以某大橋鋼管樁犧牲暘極保護工程為例，介紹犧牲暘極保護繫統保護電流密度的選取、犧牲暘極的選定及關鍵技術問題與處理措施，工程實施後測得鋼管樁保護電位值均在設計保護電位範圍之內，即-0.85～-1.10 V（相對于銅/飽和硫痠銅參比電極），鋼管樁得到瞭有效保護。
이모대교강관장희생양겁보호공정위례，개소희생양겁보호계통보호전류밀도적선취、희생양겁적선정급관건기술문제여처리조시，공정실시후측득강관장보호전위치균재설계보호전위범위지내，즉-0.85～-1.10 V（상대우동/포화류산동삼비전겁），강관장득도료유효보호。
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.
