| 摘 要： | 西宁地区次生盐渍土主要分布于山麓斜坡带高阶地和河谷高漫滩,前者属中～弱硫酸、亚硫酸盐渍土,且多具中等～强烈湿陷性,盐份主要来自斜坡后缘含盐碎屑岩风化物及易溶盐;后者为中等亚氯、亚硫酸盐渍土,溶于土中的盐份系浅层咸地下水常年毛细上升蒸发所致。其次生盐渍土的松胀性、溶陷性、腐蚀性较强,工程建设要引起重视。

| Abstract: | The secondary saline soils are mainly distributed in the piedmont slope zone,high terrace and high valley flat in Xining area. The former is middle to weak sulfuric and sulfurous saline soil with middle to strong collapsibility, its salt content mainly came fromthe salt-bearing clasolite in bake margin of slope and from the soluble salt: the latter is mid-dle chlorous and sulfurous saline soil, its salt content came from the shallow saline ground-water through capillary action and evaporation year in year out. It is necessary to pay atten-tion to the secondary saline soils in the engineering construction because of its loosening ex-pansion, collapsibility and corrosiveness. |
