该文通过对分布在全国各地近千件土样腐蚀性测试数据的分析与研究,发现我国各类土的极化电流密度及腐蚀性呈现出明显的地区特性,它不仅与土中易溶盐含量有关,而且与成土地质条件、气候等密切相关。同时根据实践经验,提出测试工作中应注意事项的建议。 Through the analysis and research of nearly a thousand pieces of soil-corrosive test data distributed all over the country, it is found that the polarization current density and corrosivity of all kinds of soils in our country show obvious regional characteristics. Content, but also with the formation of geological conditions, climate and other closely related. At the same time based on practical experience, put forward the recommendations should be noted in the test work.
