The article discusses a modified strengthening construction of the strip foundation, combined with a blind area, which makes it possible to increase the efficiency of this strengthen method. The results of experimental studies to verify the operability of structural protection measures are presented, and also to obtain the basic regularities of the stress-strain state of the foundation construction of a frameless building operated on an unevenly deformable base. The results of numerical studies for two cases are presented: strip foundation without strengthening construction, and strip foundation with strengthening construction. As a result of numerical studies, the dependences of the average vertical movements of the footing of the strengthened and non- strengthened foundation on the load, as well as its full bearing capacity in both cases, were obtained. The most effective application of this strengthening construction is in conditions in which the maximum critical pressures can be reached on certain sections of the strip foundation. For example, with significant uneven settlements along the length of the strip foundation.
Key words: uneven deformations of the base / strip foundation / strengthening construction / carrier blind area / limit load
