文摘

Surface waves are used to assess the surface condition of underground structures. The analysis is based on the variation of energy, phase velocity and group velocity of Rayleigh wave. The ability of surface waves to assess the conditions of underground structures is demonstrated. The degree of degradation of the lid of underground structures may be evaluated from the surface (without borings).
