摘要
钢筋锈蚀是造成钢筋混凝土桥梁破坏的重要原因之一,氯离子侵蚀是近海大气区钢筋锈蚀的首要因素。在Fick第二定律的基础上,基于持续荷载影响,提出了考虑温湿度因素影响下的改进的氯离子扩散模型,给出了模型各参数取值,通过两个试验,验证了模型的合理性。
Steel corrosion is one of the major causes of damage to reinforced concrete bridge, the chloride ion erosion is the primary factor for reinforcement corrosion in the of shore area. On the basis of Fick's second law, the impact on sustained load, proposed corrected chloride dif usion model under the influence of temperature and humidity factors, given the value of each parameter in model, and through two experiments to verify the rationality of the model .
