| 摘 要： | 文中对山东省17个市的常见市政金属结构的大气环境腐蚀防护现状进行了现场调查,分析了防护方法失效的原因。地理位置、温度、污染物、应力、焊接等因素直接或间接影响腐蚀防护的效果,氯离子沉积和大气污染是加速大气腐蚀防护失效的主要因素。防护方法的合理选择和防护方案的设计对于延长金属结构的使用寿命有重要作用。部分设施虽采用了较好的防护措施,但忽略了薄弱环节导致失效。其中,螺栓的腐蚀防护是一个薄弱环节,情况较为普遍。

| Abstract: | In this paper, the atmospheric corrosion protection status of common municipal metal structures in 17 cities of Shandong province was investigated, and the reasons for the failure of some protection methods were analyzed. Geographical location, temperature, pollutants, stress, welding and other factors affect the corrosion protection directly or indirectly. The deposition of chloride ions and the adsorption of air pollutants are the most important factors accelerating the failure of atmospheric corrosion protection methods. The reasonable selection of protection methods and the design of protection schemes are very important for prolonging the service life of metal structures. Good protective measures were taken for some facilities, but they failed for neglecting of weak portions. Among them, the corrosion protection of bolts is a common problem that did not receive proper attention. |
