中文摘要：

以罗布泊强氯盐渍土为研究对象,对该盐渍土进行了室内溶陷试验。试验运用单轴压缩试验双线法,通过在不同含水率和不同干密度条件下对盐渍土进行试验研究,试验结果表明：罗布泊强氯盐渍土随着含水率、干密度的增加,溶陷系数减小;随着压力的增加,溶陷系数增大。压力小于200kPa时,随着压力的增加溶陷系数增加速率较快;压力大于200kPa时,随着压力的增加溶陷系数增加速率逐渐减缓。

英文摘要：

The aims of the experiment in laboratory was conducted to analyze coefficient of collapsibility of the saline soil by using Lop Nor strong chlorine saline soil as materials. The experimental study on saline soil was carried out through different water contents and different dry densities. The result showed that the coifficient of collapsibility of Lop Nor strong chlorine saline soil decreased along with the increase of water contents,dry densties and coefficient of collapsibility increased along with the increase of the pressure. When the pressure was less than 200 kPa, the coefficient of collapsibility gradually increased along with the increase of the pressure.
