摘要
通过对天山北麓水磨河流域细土平原区硫酸(亚硫酸)盐渍土盐胀和冻胀力试验研究,发现盐-冻胀力与土干密度符合指数规律;盐-冻胀力与硫酸钠含量均符合二次抛物线规律;最大击实土干密度的情况下有较大的盐-冻胀力,对工程危害较大。
through the research for the salt expansion and frost heave of the sulfate （sulfite） saline soil located in the northern foothills of the Tianshan Valley Shuimohe basin Plain area contained fine soil, salt - frost heave force and dry soil density accord with index law; it tally twain parabola law with sodium sulfate; under the condition the biggest hit soil dry density, the frost heave force is larger which is harmful for the project.
