摘要： PURPOSE: An electrical resistivity surveying method of a bore hole is provided to survey a tunnel easily by measuring horizontal and ceiling portions as well as the lower portion of the tunnel. CONSTITUTION: An electrical resistivity surveying method of a bore hole is composed of: penetrating a bore hole on a survey target area of a tunnel; mounting a hollow pipe in the bore hole and supplying water to the pipe with a water supply pump; draining the water through an outlet and expanding a rubber tube with the water; contacting an electrode with a medium on the inner wall of the bore hole; and measuring the electrical resistivity distribution of the tunnel based on the measured value of an electrical resistivity survey system. The electrode pipe has several bodies to control the length and interval of electrodes and to eliminate the damage of equipment.
