| 摘 要： | 分析了广东某斜拉桥水泥浆防护拉索的钢丝受腐蚀以致失效的原因。指出了因包裹钢丝的水泥浆长时间不凝结且不充满，从而产生微电池原理的电化学腐蚀；而压浆材料所含的一定量的Cl-以及钢丝在拉应力作用下更加速了此腐蚀过程。

| Abstract: | The reason of the inefficiency of tie rods with fender cement paste of a certain bridge in Guangdong is analyzed. The steel bars become ineffective due to suffering corrosion. Cement paste bundling the steel bar can not condense in a long time, and the tie rod can not be filled with paste. As a result, electrical-chemical corrosion occurs similar to the principle of micro-electric cell. Moreover, Cl- in the cement paste and the tensile stress of the steel bar accelerate the process of corrosion. |
