摘要： PURPOSE:To prevent the lowering of quality of data by a method wherein probing is implemented in duplication by a CSMT method (underground probing using an artificial transmitting source) and MT method (terrestrial magnetism/ current probing) and a data by the MT method is linked among the data of the CSMT method below a frequency area at which a near field effect is generated as border to analyze an underground structure. CONSTITUTION:A measuring wire is installed on an MT-1 measuring device and an electrode is set at both ends of the length of a dipole for measuring an electric field and a magnetic field of a total 10 components. A transmitter GGT-30 is set at a distance 2,500-6,000m therefrom to probe using the dipole electrode. Below a specified frequency (100Hz-50Hz) at which a near field effect by a CSMT method is yielded, probing by an MT method using a natural signal is performed and above a specified frequency at which a near field effect is not yielded, probing by the CSMT method generating an artificial signal from a transmission field GGT-30 is performed. Thus, the underground structure is analyzed from the apparent specific resistance by replacing part of the data obtained by the CSMT method, with frequencies below the frequency at which the near field effect is provided, which the MT data.

摘要： PROBLEM TO BE SOLVED: To evaluate the injection effect of the chemical liquid of a ground-improving construction by comparing reflection intensity data obtained by a borehole televiewer layer inspection that is performed before injecting the chemical liquid with reflection intensity data obtained by the bore hole televiewer layer inspection that is performed after injecting the chemical liquid. SOLUTION: A borehole televiewer is lowered to an observation hole 5 to inspect a BHTV layer. The reflection intensity and time of an ultrasonic wave that is emitted wile the televiewer is raised or lowered by several m/minute are acquired and a hole wall is scanned three-dimensionally by the ultrasonic wave. Then, the chemical liquid of water glass solution is injected into hole wells 1-4 at an average injection pressure of 3kg/cm per a depth of 1m at a section of G.L-8m-G.L-18m. The chemical liquid permeates the inside of the ground from the injection holes 1-4 and an acquired reflection intensity changes due to the change in the physical properties of the hole wall of the observation hole 5 when the chemical liquid reaches the chemical liquid injection observation hole 5. After injection, the reflection intensity and time are acquired again by the borehole televiewer in the chemical liquid injection observation hole 5. The increase in the reflection intensity due to the change in degree of concretion is recognized.

摘要： PROBLEM TO BE SOLVED: To make it possible to easily join an optical fiber cable to a conventional polyimide-coated optical fiber cable in a suitable place and suitable position in underground survey, etc., in which the temp. changes as depth increases by constituting the outer circumference of the glass layer of the optical fiber cable with a carbon thin layer and coating the outer circumference thereof with a material coating layer. SOLUTION: The optical fiber cable 8 into which the polyimide optical fiber cable is inserted of this composite optical fiber cable is used in a place where the stratum temp. is below 350 deg.C. The optical fiber cable 9 into which the metallic optical cable is inserted is used in the place where the stratum temp. is 350 to 400 deg.C. The outer circumference of the fiber cable of such heat-resistant optical fiber cable 9 is formed as to optical fiber cable having the structure obtd. by coating the outer periphery of the fiber cable with the carbon thin layer 2 and subjecting the carbon coating to plating and coating of the metal 4. The reason thereof lies in that heat resistant threshold of the metal plated fiber is 400 deg.C while the heat resistant threshold of the polyimide coated fiber is 300 to 350 deg.C.

摘要： PURPOSE:To allow deep part probing by performing monohole type or crosshole type probing through the use of a high sensitivity tri-axial magnetometer having high S/N ratio comprising an array of uniaxial miniature coils containable in a tool. CONSTITUTION:A vertical magnetometer 2 comprising a mu metal core 11, sixteen pieces of unit pi windings 12, a feedback winding 13, and seventeen partition boards 14 is disposed in the center of a tri-axial magnetometer. Array type horizontal magnetometers 100, 200 formed by perpendicularly crossing ten pieces of coil elements 1, each comprising a core 3, a main winding 4, a feedback winding 5, a Teflon coil end 6, and an electrostatic shield 7, are disposed at the opposite ends of the vertical magnetometer 2 thus constituting a high sensitivity, high S/N ratio tri-axial magnetometer having diameter of 3 inch and overall length of 63 inch. A main output connector 15 provided on the cable connecting side of the tri-axial magnetometer is connected with a cable which is then laid down into a hole. Electromagnetic wave in audio frequency band is radiated from an oscillator and transmitted wave is captured thus transmitting magnetic field components being measured to a ground unit.
