Abstract

The paper presents calculations on stressstrain state of the pile strip foundation in the course of karst hole formation. The pile design scheme is presented as a rod elastically secured into the ground at one end while the other end has a pivotally-fixed pairing with grillage and load linearly increasing on the pile. The paper defines pile deformation (displacement, cross sections rotation angles), bending moment and strains in the pile, depending on variable z. This calculation technique makes it possible to perform the power analysis of forces acting on the pile in karst holes caused by the caving-in horizontal soil pressure, as well as to do all kinds of calculations on piles.
