中文摘要：

环境污染导致地下水含有大量腐蚀性污染物，严重影响水泥土地基的强度和耐久性。将水泥土试块浸泡在不同浓度硫酸溶液中不同龄期模拟硫酸污染，通过测试水泥土电阻率、孔隙水电阻率以及无侧限抗压强度，来研究硫酸污染对水泥土电阻率特性的影响。研究表明，水泥土和孔隙水电阻率均随着浓度的增加而减小，均随着龄期的增加而增大；结构因子随着龄期和浓度的增加而增人；无侧限抗压强度随着水泥土电阻率的增加而增大。建立了预测任意溶液浓度和龄期的水泥土电阻率公式。

英文摘要：

Groundwater has mass corrosion pollutant because of environmental pollution that has a strong impact on the strength and durability of soil-cement subgrade. The soil-cement blocks has been soaked in different concentrations of vitriol solution for various ages in the laboratory. After testing electric resistivity and unconfined compression strength, the effects of vitriol pollution on soil-cement electric resistivity are presented. The results indicate that the electric resistivity of soil-cement and pore water are decreasing with the increment of vitriol solution concentration while increasing with the increment of age; the formation factor is increasing with the increment of vitriol solution concentration and age; the unconfined compression strength of soil-cement blocks is increasing with the increment of soil-cement electric resistivity. Finally, a formula is purposed to forecast soil-cement electric resistivity at any solution concentration and age.
