ABSTRACT
The previous chapter has been devoted to the comprehension of the mechanisms governing jet diffusion and its interaction with different soils. In fact, a sound knowledge of these mechanical phenomena can be useful for a more rational application of the technique, allowing the selection of the most appropriate treatment procedure to create jet-grouted elements with dimensions and properties able to meet the design requirements. In practice, to this aim, it is necessary to correlate the jet grouting effects (i.e., column diameter and properties) to the original soil properties (i.e., grain size, shear strength) and to the treatment procedures (i.e., treatment parameters). However, because all soils are inherently heterogeneous, the mechanical and geometrical characteristics of the columns are usually variable. The variability of all properties can be conveniently considered using probabilistic distributions. To this aim, for a given discrete random variable x, the statistical parameters reported in Table 4.1 will be used.
