气候变化对中原地区桥梁碳化寿命影响研究
Research on Bridge Carbonation Life Influenced by Climate Change in Central Plains
摘要
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.关键词
