摘要： A method for identifying a frequency producing a dominant vibration response of an underground structure includes the steps of inducing controlled acoustic waves in the structure via ground, the acoustic waves varying over a predetermined frequency range, measuring vibration response associated with the structure in response to the controlled acoustic waves over the predetermined frequency range, using a measurement device in vibrational communication with the structure, detecting a dominant vibration response among measurements across all frequencies of the predetermined frequency range, and, identifying a frequency of the predetermined frequency range which produced the dominant vibration response.

摘要： A method for identifying a material of a water pipe buried below ground is provided. The method includes generating controlled vibrations in the water pipe using a vibration exciter, and detecting a vibration response associated with the water pipe in response to the controlled vibrations using a vibration transducer in vibrational communication with the water pipe. The method further includes analyzing and processing the vibration response using a vibration signal analyzer to identify the material of the water pipe based on a comparison of the processed vibration response of the water pipe to a known vibration response of a known water pipe material.
