Calculation of Bridge-Support Pile Foundations Taking Karst Deformations Into Account in the Base

Gotman, N. Z. / Evdokimov, A. G.

A numerical method is developed for calculating a pile foundation of bridge support with karst deformations forming in the base, taking into account the formation of ‘negative’ friction on the lateral surface of the piles. The bearing capacity, settlement, and stiffness coefficients of the piles are obtained as functions of the foundation geometry, pile load, settlement prior to karst deformation, distance to the roof of the rocky karst soils, and calculated cavity diameter.
