Abstract
Abstract Research in the stabilization of clay especially quick (sensitive) clays carries out in various institutes in Sweden (e. g. SJ, SGI and SU). Todays result shows that the sensitivity of a clay may be reduced by adding metallic salts. When added, the remolded shearing strength (τr) increases but at the same time also a certain tendency towards an increase of the undisturbed shearing strength (τf) is traced. Furthermore analysis of results obtained show that the sensitivity might be considerably reduced, if the water content could be reduced and the liquid limit (wL) be increased. The liquid limit is affected by addition of metallic salts and the water content by electrical injection. The metallic salts can be supplied by vertical wash bored holes (vertical stabilization). It is ecconomically of big account to know, which salts could be used. Swedish experiments show that univalent salts might be most unsuitable and trivalent salts most suitable. However, good results has been achieved in Norway with univalent salts. Far-reaching scientific work is necessary to reach cheaper and more effektive vertical stabilizations.
