土壤电阻率测试常见问题的分析

土壤电阻率的测试方法目前运用较为广泛的是四极等距法(文纳四极法),该方法测试数据较准确,操作过程较为简单,但由于测试现场土壤状况非常复杂,若对测量仪器和原理不深入了解或测试场地选择不当,将无法得到准确的数据,同时在测试过程中,测试人员通常会遇到数据偏小或数据超过仪器量程而导致无法运用到具体的工程和评估计算中,为此对测试场地、仪器的选择,数据无法测出的问题,测试电极的埋设深度,测试电极"a"的选择等常见问题提出最佳解决办法。

Analysis of Familiar Questions About Measuring of Earth Resistivity

The soil resistivity testing method is currently using a wide range of is quadrupole isometric method(Wenner's four-electrodemethod),this method test data accurately,operation process is simple,but due to the test site soil conditions are very complex,the principle of measuring instruments and if not thorough understanding or test site selection undeserved,will not be able to get accurate data,at the same time during test,testers will usually meet data slants small or data more than instrument range and can...
