摘要:
针对气候变化背景下的混凝土碳化问题，以郑少高速南水北调大桥辅线桥为研究对象，依据联合国政府间气候变化专门委员会( IPCC)最新研究报告，建立郑州地区在高、低两种碳排放情景下气候边界模型。基于该模型研究了温度、大气湿度以及二氧化碳浓度在未来100年间的发展规律，以此来预测辅线桥主梁和桥墩的碳化寿命，最后通过与恒定气候参数下的碳化寿命计算结果进行对比。结果表明：气候变化将在一定程度上影响中原地区桥梁碳化进程，高排放情景下主梁和桥墩的碳化寿命较之于低排放情景将缩短13%左右。
Abstract:
This paper aimed to explore the concrete carbonation problem under climate change, based on birdge connecting Zhengshao Highway to Hanghai Road project,by simulating climate boundary models in high emission situation and low emission situation of Zhengzhou according to the latest research report by Intergov-ernmental Panel on Climate Change. The model predicted carbonation life of beam and pier by setting up de-velopment trends of temperature, humidity and CO2 concentration in the next 100 years accor models. Com-pared with carbonation life calculated by constant climate parameters. The results showed that climate change would affect bridge carbonation process in central plains to a certain extent. Compared with low emissions situa-tion,carbonation life of beam and piers would be shorten about 13% in high emissions situation.
