Estimating the Elastic Settlement of Vertically Loaded Single Piles in Rock

Article Preview

Abstract:

An extensive finite element analysis was performed to study the settlement behavior of vertically loaded piles entirely embedded in non-homogeneous rock. To avoid utilizing interrelated parameters, pile-rock relative stiffness was expressed as a function of the elastic modulus of rock mass near the pile head that does not depend on pile length. Cases of pile-rock stiffness ratios that are typical for reinforced concrete piles bored in sedimentary rocks were investigated. Charts were developed to predict the elastic settlement of vertically loaded piles in non-homogeneous media. An equation was also introduced to incorporate the effect of rock non-homogeneity in estimating the depth at which settlement becomes insensitive to the increase of pile length.
