Lodigina N., Sharapov R. Calculation of pile foundations at the karst areas // Proceedings of the 2014 IEEE International Conference on Mechanical Engineering, Automation and Control Systems (MEACS 2014), 16-18 October 2014, Tomsk, Russia. 2014. P. 1-4.

The paper presents calculations on stress-strain 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
