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