本文以不同含氯量的实际氯盐渍土及自制单Na Cl盐土作为固化土样,采用矿渣(KC)作为固化剂对上述土样进行固化,通过固化土无侧限抗压强度测试,探讨KC固化氯盐渍土的强度变化规律。试验结果表明:氯盐渍土中的Na Cl是影响KC固化氯盐渍土强度的最主要因素,KC固化氯盐渍土强度随氯盐渍土中含氯量增加而增加。以此为基础,通过对固化土强度增量的回归分析,得到KC固化氯盐渍土强度增量与含氯量之间的关系式。

In this paper, the actual chlorine saline soil with different chlorine content and self-made single Na Cl salt soil as the solidified soil samples, the use of slag (KC) as a curing agent for curing the above soil samples, through unconfined compressive strength of soil test Strength of KC solidified chloride saline soil. The results showed that NaCl in the saline soil was the most important factor affecting the strength of the chlorinated saline soil. The strength of the chlorinated saline soil increased with the increase of chlorine content in the saline soil. Based on this, by regression analysis of the increment of the strength of the cured soil, the relationship between the strength increment of the chlorinated saline soil of KC curing and the chlorine content was obtained.
