| 摘 要： | 盐湖地区钾、钠、镁、锂、气资源丰富,盐湖资源的综合开发利用越来越受到人们的重视.但盐湖地区土环境中Mg^2＋、Cl^-、SO4^2-离子含量高,对混凝土和钢结构的侵蚀破坏非常严重.通过化学和电化学检测手段,分析了盐湖地区几个典型地点土的电阻率、含盐量、pH值、氯离子含量和硫酸根离子含量等理化指标,根据相关标准分析评价了盐湖地区土的腐蚀性,评价结果表明,该盐湖土属于强腐蚀土.

| Abstract: | Potassium, sodium, magnesium, lithium, gas and other resources are rich in salt lake area, so comprehensive development and utilization of salt lake resources is getting increasing attention. However, Mg2＋ .CI-and SO42- ion content is very high in the soil environment of the salt lake area, which can make serious erosion and damage to concrete and steel. By means of chemical and electrochemical detection, physical and chemical indicators such as soil resistivity, soil salinity, soil pH, chloride ion content and sulfate ion content in several typical locations of the salt lake area are analyzed. Soil causticity in the salt lake area is analyzed and evaluated in accordance with relevant standards, the results show that the salt lake soil belongs to highly corrosive saline soil. |
