PURPOSE: A TDR measurement wire and a TDR measuring system including the same are provided to sensitively sense an internal change like a slope ground, a cutting area, and rock etc. and prevent a noise which is caused by underground water. CONSTITUTION: A TDR measurement wire(100) includes multiple conductor wires(110); an insulation coating member(120) of insulation material which covers the conductor wires; and a shielding layer(130) which is equipped inside of the insulation coating member, surrounds the conductor wires, and prevents a flux which is generated in the conductor wires from leaking to the outside of the insulation coating member when an electric pulse flows in multiple conductor wires. |
