FLUID WAVE PROPAGATION IN SATURATED AND NEARLY SATURATED SANDS. DISCUSSION AND CLOSURE

The discussers comment on the possibility suggested in the original paper of using the in situ compression wave velocity from seismic tests as a way of determining if a cohesionless soil below the groundwater table is fully saturated or just nearly saturated. The discussers also note cases where low P-wave velocities were measured down to some depth below the existing water table and where supplementary data suggest that the material should not have been saturated down to this depth. The author of the paper accepts the comments made by the discussers and points out the significance of the fact that the occurrence of the piezometric surface, in incompletely saturated soils, at elevations different from that identified by the P-wave velocity for saturated materials may lead to unpleasant surprises during construction. It is also noted that interpretations of refraction seismic tests should always be cross-checked with water table evaluations.
