... geophysics monitoring strain Drying and drying–wetting cycles can lead to the formation of desiccation cracking in clayey soils. The presence of cracks adversely affects mechanical and hydraulic properties of soils, leading to a series of geological, geotechnical, hydrological and environmental...

... behaviour, however, has hitherto been proposed. This paper explores to what extent the participation of finer particles can be assessed using laboratory geophysics, recognising that granular materials act as a filter to remove the high-frequency components of applied seismic/sound waves. Discrete-element...

However, these tagged detection methods can only reveal that the jet grouts have reached the marked location, but the actual formation of cement grout remains unknown. Following the development of geophysical methods, subsurface imaging techniques have been...
