| 摘 要： | 跨海桥承台采用钢底板封底,诸多因素使得钢底板与钢管桩之间绝缘性难以保证。钢底板为裸钢,连入钢管桩阴极保护系统影响较大。分析电阻法测量法不能准确判断钢底板与钢管桩的电连接的原因,认为采用半电池电位法测量更为可靠,同时分析钢底板对钢管桩阴极保护的发射电流和使用寿命的影响程度,提出相应的补救措施。

| Abstract: | Since the pile caps of sea-crossing bridge use steel plate at bottom,there are many factors that make it difficult to ensure the insulation between the steel bottom plate and steel pipe piles.Because the steel bottom plate is of bare steel,and the connection with steel pipe piles leads to a greater effect on the cathodic protection system.It is believed that the use of half-cell measurement method is more reliable because the analysis resistance measurement method can not accurately identify the reason of e... |
