天然强氯盐渍土盐--冻胀性试验研究

以罗布泊盐渍土为研究对象，通过室内试验对其盐一冻胀性进行了研究，盐渍土的盐-冻胀性试验在冻融循环条件下进行，试验结果表明，罗布泊强氯盐渍土的累加盐-冻胀率随冻融次数的增加而逐渐增大；相同干密度时含水率为最优含水率的土样，其累加盐-冻胀率最大；相同含水率不同干密度的土样，其盐-冻胀率相差不大；含水率的变化对盐渍土的盐一冻胀率影响较大。

Test research on salt-frost heaving of natural strong chlorine saline soil

Taking Lop Nor saline soils as the research object, through the indoor test made research on salt-frost heaving. The salt-frost heaving test of saline soil was proceed under freeze-thaw cycle conditions, the test results showed that, the accumulated salt-frost heaving ratio of Lop Nor strong chlorine saline soil salt increasing with the numbers of freeze-thaw, the salt-frost heaving ratio was largest when the moisture content was optimum in same dry density, the same water content rate dry density soil, its salt-frost heaving ratio had little difference, the water content change had big iiffluence to salt-frost heaving ratio of saline soil.
