The method of measuring soil porosity by electrical resistivity has been developing vigorously in recent years;it has been applied in engineering geology , hydrogeology , environmental monitoring and other fields .This paper presents a method of quantitatively determining saturated sand porosity with electrical resistivity by porosity change law in the process of sand liquefaction .Different forms of test probes are used in comparison test trials , and electrical resistivity test probe for the specific soil box is selected and determined .Based on the theory of two-electrode and four-electrode method,a series of comparative tests are completed by changing the electrode type ( copper sheet , brass wire mesh , fine copper bar ) and controlling electrode spacing , penetration depth , voltage etc.The appropriate test electrode and the test method can be determined by these tests and the above test condi -tions affecting resistivity test results have been discussed .The foundation will be laid for investigations on the law of porosity change in the process of sand liquefaction .
