项目摘要
An evaluation system for the lifecycle cost and the lifecylce-environmental load of bridges was established in this study. This system was applied to several bridges and the availability was investigated. Special attention was paid to the shortage of the information on the environmental effects on the lifecycle of the members of bridges. In order to obtain the fundamental data, accelerated exposure tests were 'then carried out focusing on the corrosion of steels. The variation of the weight decrease, the mean amount of thickness decrease, and the maximum of the amount of thickness decrease due to the corrosion were investigated. It was shown that the variation of weight decrease and the variation of thickness decrease were expressed with involution functions for time. Comparing the results of the exterior exposure tests and those of the accelerated exposure tests, the acceleration coefficients on the corrosion in these two tests were calculated. Correlation analysis between the amount of flying salt and the acceleration coefficients was conducted. The result insisted that the acceleration coefficients were highly correlated to the amount of flying salt and its relationship was able to be expressed by an involution function.
建立了桥梁全寿命周期费用和全寿命周期环境荷载的评价体系。将该系统应用于多座桥梁,并对其有效性进行了研究。特别注意的是,缺乏有关环境对桥梁构件生命周期影响的信息。为了获得基础数据,然后进行了加速暴露试验,重点是钢的腐蚀。研究了由于腐蚀引起的重量减少、平均厚度减少量和最大厚度减少量的变化。结果表明,重量减少量的变化和厚度减少量的变化均用时间的对合函数表示。通过比较室外暴露试验和加速暴露试验的结果,计算了两种试验条件下的加速腐蚀系数。并对盐量与加速度系数进行了相关分析。结果表明,加速度系数与飞盐量高度相关,其关系可用一个对合函数表示。
