StoneC is a software that performs design calculations of vibro replacement. Vibro replacement is an accepted method for subsoil improvement, that is achieved with the installation of large columns of coarse backfill material in the ground, using special vibrators. StoneC was tested for accuracy by The Vibroflotation Group and was found to perform well.
SPTCorr is a simple software for estimating various soil properties from the Standard Penetration Test blow count. SPT is a widely and most frequently used in-situ test for geotechnical exploration. It is useful in a wide variety of soils, from weak clays and loose sands to dense sands and hard clays. SPTCorr provides results from what are considered to be the most useful and reliable correlations between SPT blows and soil properties.
