随着国民经济建设的发展,我国目前已有大量的各种金属结构物埋设在土壤中.在今后的几个五年计划期间,还将兴建成千上百个大中型工程项目,大部分这类工程项目,都有相当数量的各种地下管道、电缆、钢桩、钢筋混凝土基础等要埋入土壤中.如何控制这些地下金属结构物的腐蚀损伤并延长其使用寿命,对整个工程的正常发挥作用具有十分重要的意义.因此,土壤腐蚀与防护的研究,是一项与国民经济建设关系十分密切的工作.
With the development of the national economy, a large amount of various metal structures have been planted in the soil in our country and thousands of large and medium-sized projects will be built during the next five-year plans, most of which There are a considerable number of underground pipelines, cables, steel piles and reinforced concrete foundations buried in the soil, etc. How to control the corrosion damage and extend the service life of these underground metal structures, and the normal operation of the entire project Therefore, the study of soil erosion and protection is a work closely related to the national economic construction.
