研究了含盐量和水泥掺入量对水泥固化的连云港海相软土试样无侧限抗压强度影响规律.人工掺入不同含量的氯化钠制备含氯盐软土,并采用硅酸盐水泥固化处理,在标准条件下养护28d后进行无侧限抗压强度试验.研究结果表明:掺入氯化钠盐将会降低固化土的无侧限抗压强度,且固化土强度随着含盐量的增加而降低.固化土孔隙率和含盐量的乘积与水泥掺入量的比值可以综合反映含盐量和水泥掺入量对固化土无侧限抗压强度的影响规律,并可采用一经验公式描述水泥土无侧限抗压强度和影响因素之间的关系.该研究可为高含氯盐软土固化处置技术方案评价提供参考.
The effects of salt content and cement content on the unconfined compressive strength of liquefied soft clay samples of Lianyungang seawater were studied.The NaCl-containing soft soil with different content of artificial sodium chloride was prepared by artificial mixing method and silicic acid Salt cement curing treatment under standard conditions for 28 days after unconfined compressive strength test.The results show that: the incorporation of sodium chloride salt will reduce the unconfined compressive strength of the soil, and the strength of the soil with the The ratio of the product of porosity and salinity of solidified soil to the amount of cement incorporated can reflect the influence law of unconfined compressive strength of solidified soil with salt content and cement incorporation An empirical formula can be used to describe the relationship between unconfined compressive strength of cement-soil and its influencing factors. This study can provide reference for the evaluation of technical solutions of high chloride-containing saline soil consolidation.
