Abstract: A pyrotechnic method for stabilisation of low bearing capacity subsoil, that consists of determination of the parameters of the layer of soil to be stabilised, drilling nontabulated, vertical shot-holes at the intersection points of a square or equilateral triangle grid, selection, preparation and firing the oblong charges, characterised by the fact that the shot-holes with a diameter from 0.02 to 1.5 m and a depth of up to 50 m, are drilled with a water flush or a mud or clay suspension, at a spacing of 3 to 25 m, this spacing distance being inversely proportional to the thickness of the layer of soil that is to be stabilised. The charges, the total length of which cannot exceed the thickness of the layer to be consolidated, are composed of several small “sub-charges”, spaced at distances from 1 to 10 m down the shot hole. The bottom end of each charge is blocked with a rod the diameter of which is greater than that of the shot hole.
