摘要
分析大口径顶管穿越段管道阴极保护存在的问题。结合工程实例,对大口径顶管穿越段管道和紧固件牺牲阳极阴极保护方案进行探讨。
The problems existing in the cathodic protection of large-diameter pipe jacking crossing section are analyzed.Combined with engineering examples,the sacrificial anode cathodic protection scheme of large-diameter pipe jacking crossing section and fasteners is discussed.
