ABSTRACT
As already pointed out in Chapter 5, jet grouting is frequently used for many different goals by arranging the columns in various possible ways to create one-, two-or three-dimensional elements. It follows that present design procedures for foundations, retaining structures, water barriers, tunnels, etc., should be properly adapted to encompass the use of jet grouting as a possible alternative to conventional bored or driven rigid elements (e.g., piles, walls, etc.). Table 6.1 summarises the most frequent applications of jet grouting, pointing out the role played by the jet-grouted structure, the typical geometrical configurations, the needed geometrical and mechanical characteristics of the columns and the assessments to be carried out.
