| 摘 要： | 西园隧洞原设计为水工隧洞,选用的混凝土材料不具有抗酸性,在增加了排污功能以后,洞体内含有大密度的硫的氧化物和二氧化碳。这些有害物质与衬砌混凝土发生化学反应,是混凝土发生腐蚀碳化的最根本和最直接的原因。

| Abstract: | The paper analyzes carbonization corrosion reasons of lining concrete in Xi Yuan Tunnel,Dianchi.The concrete material,which has been selected according to original design,was the material without acid resistant capabitity.After the increased function of dumping pollutants,the great density sulfur oxide compound and the carbon dioxide in the tunnel,which has been reacting with the lining concrete,are the most basic and direct reasons of the concrete carbonization. |
