摘　　要：为了研究电极敷设方式对土壤电阻率测试结果的影响,采用数值模拟分析拟合法以及样本实测法,通过改变测试桩间距、增加测试桩深、测试桩与土壤接触面积等几个方面,对土壤电阻率开展研究。研究结果表明:电极接触程度、电极间距和电极布置形式等因素均对测试结果产生影响,增加测试桩距可有效降低测试误差;增大测试桩的深度,对浅层土壤的测试结果影响较大,其布桩方式会增大实际土壤电阻率的数值;增加测试桩与土壤的接触程度,在其他条件不变的情况下,可有效降低土壤电阻率的测量误差。通过反演土壤电阻率结果可知,选用合适的测试桩深度,可以有效降低测量误差,得出更为精确的测量结果。To explore the influence of electrode laying methods on the soil resistivity test results,numerical simulation analysis fitting and sample measurement methods are used to conduct research on soil resistivity from aspects such as changing the spacing of test piles,increasing the depth of test piles,and increasing the contact area between test piles and soil.The research results show that factors such as the degree of electrode contact,electrode spacing,andelectrode arrangement all have an impact on the test results.Increasing the test pile spacing can effectively reduce the test error;increasing the depth of the test pile has a greater effect on the test results of shallow soil,and its pile-laying method will increase the value of the actual soil resistivity;increasing the degree of contact between the test pile and the soil can effectively reduce the measurement error of soil resistivity under the condition that other conditions remain unchanged.From the results of soil resistivity inversion,it can be seen that selecting an appropriate test pile depth can effectively reduce the measurement error and obtain more accurate measurement results.
