Modification of Soil Beds by the Method of Compensation Injection

A man-made bed for structures, which is formed by injection of grouts with a break in the continuity and compaction of the surrounding soil, is examined. It is established that where the heterogeneity of a geocomposite as a medium is high, the bed of which as an element of the "structure-bed" system exhibits a high degree of homogeneity. It is noted that methods adopted in regulatory documents do not permit determination of the mechanical properties of a geocomposite. Methods are cited for determination of the allowable pressure on a geocomposite and its compression modulus.
