摘要： PROBLEM TO BE SOLVED: To provide a ground saturation degree measuring method in which a saturation degree can be measured easily, quickly and reliably with high accuracy while keeping a water retention state, in which a saturation degree at an original position is kept, without taking out a collected undisturbed specimen.SOLUTION: An undisturbed specimen 3 at a bottom of a borehole 11 is collected with a sampler 2 provided at a tip of a rod 1, and thereafter the sampler 2 is taken out by lifting it from the borehole 11 while maintaining a water retention state kept with a water retention tool 4. A sampler 2 is taken out of the water retention tool 4 in a state that the water retention tool 4 is kept under water contained in a container 7 on the ground, and the sampler 2 is dismantled to take out a tube 2a storing the collected specimen 3. A total length of the collected specimen 3 is measured while keeping the state that the tube 2a is under the water, and thereafter the tube 2a storing the collected specimen 3 is loaded inside the measuring container 13 also kept under water, and sealed. The measured container 13 is taken out of the water and a mass of the collected specimen 3 is measured, and thereafter a saturation degree is obtained by measuring the mass and volume of soil particles of the collected specimen 3.

摘要： PROBLEM TO BE SOLVED: To provide a method for measuring the degree of saturation of ground, which enables high-precision measurement when the degree of saturation of the ground is measured on the basis of specific resistance of sand ground undergoing injection of air so as to prevent liquefaction.SOLUTION: A long hole H is drilled by a drilling rod through the use of drilling water with specific resistance within an allowable range preset with respect to specific resistance of in-situ groundwater, and electrodes 6 are installed in the long hole H. The degree of saturation of sand ground, into which air A is injected through an air injection pipe 3, is measured on the basis of the specific resistance detected between the electrodes 6.

摘要： PROBLEM TO BE SOLVED: To provide a method for measuring the degree of saturation of ground, which is employed for a ground liquefaction prevention method for unsaturation degree of the ground by injecting air into the ground, which makes the degree of the saturation of the whole prescribed ground measured in a two-dimensional or three-dimensional manner, and which enables the degree of the saturation of the ground to be accurately measured by a combination of two types of measuring methods.
SOLUTION: The degree of the saturation of the ground is measured by measuring a dielectric constant of the ground by means of a dielectric constant measuring device. Additionally, the degree of the saturation of the ground is measured by measuring a rate of change of specific resistance of the ground by means of a specific resistance tomography measuring device. A correlation between the degrees of the saturation of the ground is derived from the result of measurement by the specific resistance tomography measuring device and that of measurement by the dielectric constant measuring device. The result of the measurement by the specific resistance tomography measuring device is calibrated on the basis of that of the measurement by the dielectric constant measuring device.
