【摘要】 应用二相电极法研制了低频交流电阻测试仪,对南京工业污染土进行了电阻率随温度变化的试验测定。结果表明,随着温度的升高,污染土电阻率降低,电阻率随温度的变化呈良好的对数关系。结合目前应用较多的温度校正Keller和Frischnecht法和Campbell法,提出了最理想校正温度法,并推导出了相应的计算公式。试验证明,对于污染土,最理想校正温度法比Keller和Frischnecht法和Campbell法效果更好,拟合精度更高。更多还原

【Abstract】 A low frequency alternating current resistance instrument is developed for measuring the resistivity of the contaminated soil.The contaminated soils were sampled at the industry areas of Nanjing.With the instrument,the resistivity varying with the temperature is mensurated for the contaminated soil in Nanjing.The testing results show that the resistivity of the contaminated soil reduces with the temperature hoisting.It is a good logarithm relation between the resistivity and the temperature.The best ideal revising temperature method is presented base on the Keller and Froschnecht method and the Campbell method.At the same time,the rivising formula is deduced.The experiment results show that the method is more better than the Keller and Frischnecht method and the Campbell method for the contaminated soil.更多还原
