为研究水泥稳定土处置盐渍土软弱地基问题,考虑水泥掺量、含盐量和含水率三因素,进行水泥稳定土28d无侧限抗压强度试验。正交试验分析表明,水泥稳定土中含盐量的多少显著影响其无侧限抗压强度的大小;水泥掺量、含水率的改变对试件的无侧限抗压强度有一定影响,试件强度随着水泥掺量的增加而增大,随着含水率的增大而减小,其变化幅度均不明显;水泥掺量与含水率的交互作用也显著影响着水泥稳定土的无侧限抗压强度。
In order to study the problem of cement stabilized soil disposal of soft soils in saline soils, unconfined compressive strength tests of cement stabilized soils for 28 days were carried out considering three factors of cement content, salt content and water content. Orthogonal test analysis shows that the amount of salt in cement-stabilized soil significantly affects the unconfined compressive strength; the change of cement content and water content have some influence on the unconfined compressive strength Strength of cement increases with the increase of cement content, and decreases with the increase of water content, but the change range is insignificant. Interaction between cement content and water content also significantly affects the cementless soil Compressive strength.
