The article solves the problem of stress and strain state of the subgrade waned by cylindrical neckline, modeling the karst pothole area. The solution was obtained taking into account nonlinear behavior of the soil subgrade based on using the A.I.Bonkin bilinear subjection. In the article are presented the visual results of calculations as the isofields of stresses and strains. The obtained solution allowed us to offer for consideration an updated analytical model of karst-resisting foundations of buildings and constructions. In the proposed analytical model was adopted a variable coefficient of subgrade reaction, varying according to the bilinear law.
