摘要
钢筋混凝土井壁的耐久性研究对井壁的安全运行意义重大。文章在调查的基础上提出了井壁周围的地下水中含有的盐害离子的种类,分析了混凝土的化学成分,研究硫酸盐、碳酸盐腐蚀混凝土的机理及类型;研究氯盐腐蚀钢筋与混凝土的类型与危害。结果表明盐害离子对钢筋混凝土井壁极具腐蚀性,是井壁耐久性的隐患。
The study on the reinforced concrete durability rosion mechanism about salt disasters such as SO4 2-, CO3 2- is water and soil, which the chemical components of concrete is are analyzed. The results show： the salt disasters attack shaft reason of shaft lining durability descending. was important to the shaft linging operation. The cor analyzed on the basis of analysis of shaft linging near analyzed too. The corrosion types and damage of CI lining reinforced concrete heavily ,which is the main
