Multi-channel active measurement of the surface wave to estimate shear wave velocity profile

Apstrakt

Requirements for equipment, survey procedures, data analysis, and reporting for active measurement of surface wave exploration, which is a non-destructive testing method that uses multiple sensors placed on the ground surface, are specified.

This standard is applied to multichannel surface wave exploration for estimating one-dimensional shear wave velocity. Specifically, a method for estimating S-wave velocity profile by processing records of artificially generated Rayleigh waves based on the fundamental mode is described.

The application is only for soil ground investigation. Applications of surface wave exploration to non-soil ground, such as diagnosis of asphalt roads at depths of several centimetres or the diagnosis of metal plate deterioration, are not covered in this standard.
