摘要： PROBLEM TO BE SOLVED: To provide an internal defect detection device of a structure capable of detecting surely a fine internal defect in an initial stage of damage progression in a structure such as a concrete structure, for example, in an initial stage caused by deterioration such as a freezing damage or neutralization, and contributing surely to preventive maintenance management of the concrete structure.
SOLUTION: An elastic wave oscillation part is formed on the structure, and an elastic wave reception part for receiving the elastic wave oscillated from the elastic wave oscillation part is also formed. An elastic wave is oscillated from the elastic wave oscillation part and the oscillated elastic wave is received by the elastic wave reception part. Then, the ratio between the amplitude or energy of an elastic wave oscillation wavelength and the amplitude or energy of an elastic wave reception wavelength is acquired as an attenuation ratio, and an internal defect and/or an internal defect spot of the structure is detected from the acquired attenuation ratio.

摘要： PROBLEM TO BE SOLVED: To provide a crack depth measurement method for correctly measuring a crack depth formed from a surface of a hardened cement object to the inside. SOLUTION: In the crack depth measurement method, the crack depth is calculated by the first formula: d=-α×λ×InF. In the first formula, the d is the crack depth (mm), and the λ is a primary wavelength (mm). The F is an amplitude ratio obtained by dividing the second minimum negative amplitude fluctuated toward the negative side right after a surface wave is initiated among the second surface waves propagated on a surface of the hardened cement object and detected in a second sensor 13 by the first minimum negative amplitude fluctuated toward the negative side right after the surface wave is initiated among the first surface waves propagated on the surface of the hardened cement object and detected in a first sensor 12, and the α is a constant (0.381) calculated from an approximate expression: y=αe bx derived from a correlation diagram for indicating the (F) along a vertical axis, and a ratio of the crack depth (d)/the primary wavelength (λ) along a horizontal axis.
