| 摘 要： | 通过对天山北麓水磨河流域细土平原区硫酸（亚硫酸）盐渍土有荷载多次冻融盐-冻胀试验研究,发现不同硫酸钠含量、不同压力土体多次冻融盐-冻胀变形随冻融次数的变化规律是土体膨胀力、土体抵抗力、外压力综合作用的结果。不同压力、不同硫酸钠含量土体冻融循环次数与土体盐-冻胀干密度和土体盐-冻胀率均符合二次抛物线规律。

| Abstract: | Through the test research of multiple freeze-thaw and salt swelling and frost heave of sulfuric acid(sulfite) saline soil located in Shunmohe basin of the north toe of Tian Mountain under the loads,it found under different sodium content and different pressure the variation law of multiple freeze-thaw and salt swelling and frost heave deformation of the earth body with the variation of the numbers of freeze-thaw is the combined result of the expansive force,soil resistance and external pressure.The numbers ... |
