盐渍土地基处理的浸水试验研究

盐渍土作为一种不良土体,由于它的盐溶特性严重影响置于其上的建筑物。采用何种有效的处理方法来降低溶陷沉降量将至关重要。文中以西北某盐渍土机场的地基处理为例,采用浸水预溶的处理方法,在现场分别进行了深层浸水试验、直接浸水试验、浸水后晾晒试验,并对施工工艺、浸水控制、渗水速度确定做了研究。通过试验后检测,浸水预溶试验取得了良好的效果,为指导大面积地基处理施工提供了可靠参数。

Study on Soaking Test of Treated Saline Ground

As a kind of harmful ground,the salinine ground causes many damages to the buildings.It is important to treat saline ground to decrease the dissolved subside.With the example of saline soil ground treatment of airfield in northwest,the on-the-spot tests of soak-ing,drying,technology and controlling are studied.The result of treatment is well acquired according to checking.At the same time,the success is acquired in the application of the project.
