| 摘 要： | 电阻率法作为一种简单有效的测试方法,已在岩土工程检测中得到了一定程度的应用.通过室内试验模拟了水泥土试块受不同浓度硫酸溶液污染的反应,采用电阻率法研究了孔隙水电阻率、水泥土电阻率、结构因子与溶液浓度和龄期之间的关系.结果表明,孔隙水和水泥土电阻率随溶液浓度增大而减小、随龄期的增大而增大,结构因子随着溶液浓度和龄期的增加而增加,它们之间具有较高的相关性.这充分说明,电阻率法可应用于硫酸污染水泥土的检测和评价.

| Abstract: | As brief and effective, the method of electrical resistivity has been used in geotechnical engineering to a certain degree. Based on a series of experiments that soil-cement block polluted by various concentrations of H2SO4 solution in lab, the relations among electrical resistivity of soil-cement and pore water, formation factor and solution concentration were studied by using electrical resistivity method. The results indicate that both of electrical resistivity and formation factor have close correlations with H2SO4 solution concentrations and age time. This shows that the electrical resistivity method is feasible to test and evaluate soil-cement polluted by H2SO4. |
