This is a discussion of a paper of this title by T.D. Smith in Volume 113, No. 9 (September 1989) issue of this journal. The discusser Chugh disagrees with the authors discouragement of the Terzaghi semi-empirical horizontal subgrade reaction coefficients for pile problems. The Discusser Horvath notes that the Winkler hypothesis does not model correctly the load-transfer mechanism between a laterally loaded deep-foundation element and the soil surrounding it. The state of the art in subgrade models for laterally loaded deep foundation elements is defined by the theory of elasticity. The state of practice with regard to laterally loaded deep-foundation elements should be advanced closer to the state of the art by adoption of a subgrade model that addresses explicitly the two components of pile-soil interaction described by the author. The discussions are folowed by a closure by the author.
