测试方法及试件深度对水泥体视电阻率的影响研究
|
摘要
本文分别采用二电极法和四电极法对水泥体视电阻率进行测试研究,对比分析两种测试方法在测量结果上的区别;采用四电极法测试不同深度水泥体试件的视电阻率,探究试件深度对测试结果的影响。分析表明:对于水泥体试件的视电阻率,二电极法测试结果偏高于四电极法,四电极法测试结果相对稳定,当电极距为5 cm,水泥体试件深度小于15 cm时,测试结果将偏高且不稳定。
In this paper, the apparent resistivity of cement was measured by two-probe method and four-probe method, and the difference between the two test methods was compared and analyzed in the measurement results. The four-probe method was used to test the apparent resistivity of different depth cement sample, and the influence of the depth of the sample on the test result was investigated. The analysis showed that as to the apparent resistivity of the cement piece, the result of the two-probe method is higher than that of the four-electrode method. When the electrode distance was 5 cm and the depth of the cement piece was less than 15 cm, the test results could be higher and unstable than that of the four-prode method.
