Device for evaluating characteristics of target ground containing metal component

A device for evaluating characteristics of a target ground containing a metal component, the device comprising:

• a penetration probe having a main frame and a pair of side frames respectively installed at opposite side ends of the main frame, wherein each side frame has a lower end thereof extending downward from the main frame;
• four electrodes installed on the main frame and exposed to outside on the main frame;
• an electrode measurement part for measuring apparent chargeability of the target ground;
• and
• a main processor for calculating a weight ratio of the metal component of the target ground on the basis of the apparent chargeability measured by the electrode measurement part and calculating a volume ratio of the metal component of the target ground on the basis of the calculated weight ratio of the metal component,
• wherein the electrode measurement part applies power for measurement to two electrodes among the four electrodes, and detects voltage between the other two electrodes, and then measures the apparent chargeability through a time domain induced polarization probe method using the detected voltage,
• wherein the weight ratio of the metal component is subjected to a type of the metal component, so as to be proportional to the apparent chargeability, and
• wherein the volume ratio of the metal component is calculated based on the weight ratio of the metal component, specific gravity of the metal component, and specific gravity of a soil component of the target ground.
