The discusser of the above paper reports a comparison made at a nuclear power plant site where both the Vibroflot and the Terra-Probe were used to densify an alluvial deposit. A comparison was also made of the effectiveness of the Vibroflot used at 2 different nuclear power plant sites with different degrees of success. Comments are made regarding the findings, and it is concluded that the Terra-Probe and the Vibraflotation under similar conditions work equially well. The Terra-Probe has a lesser zone of influence than the vibroflot. Complete coverage with Terra-Probe provings is often necessary and results in densities almost as high as those produced by vibroflotation with average spacing. The productivities are similar with a slight cost advantage for the Terra-Probe. Further conclusions are presented which relate to the gradation of the in-situ material and their effect on the succes of the 2 methods, the proximity of the water table, offshore densification, and the need for backfill.
