新疆S301某路段盐渍土基本性质试验研究

Experimental study on the basic properties of saline soil on a section of S301 in Xinjiang

选取S301部分路段盐渍土为研究对象,为研究其基本性质,取不同深度的盐渍土进行试验,通过对盐渍土试样的室内试验,结果表明:S301沿线盐渍土种类较多,无明显规律,盐渍土种类有氯盐渍土、亚氯盐渍土和亚硫酸盐渍土;盐渍土在洗盐后会随着易溶盐含量的减少其塑性指数增加;由室内击实试验结果得出,盐渍土的含水率变化时,土体的最大干密度的变化较敏感。

In order to study the basic properties of salt soil in section S301,the salt soil of different depths was tested. The results showed that there were many salt soil types along S301,and there was no obvious law. The type of saline soil include chlorinated saline soil,chlorinated saline soil and sulfite. The plasticity index of saline soil increased with the reduction of salt. The maximum dry density of saline soils is sensitive to the change of water content.
