Analysis of piles in rock

A review of research on the performance of piles in rock is presented. It is demonstrated that the bearing capacity of a pile is determined not only by the uniaxial compressive strength of the rock in its bed, but also by such factors as the ratio of the diameter of the pile to the depth of its embedment, the ratio of the compression modulus of the rock mass to the elastic modulus of the concrete pile, and the conditions at the contact between the lateral surface of the pile and rock, as well as procedural characteristics of the work performed in installing the piles.
