Abstract

Although the ground supporting the foundation can be regarded as three-dimensional nonlinear continuous body, in design, grounds are modeled as linear elastic springs. However, in reality, grounds exhibit nonlinear load-displacement (ρ-δ) characteristics. In Specifications for Highway Bridges (Japan Road Association, 1994), ground reaction coefficient is defined as the secant slope of noticeable displacement and load intensity on ρ-δ curve corrected according to width of foundation. For the purpose of examining the scale effect of large-diameter pile, this paper presents a study on scale effect of lateral ground reaction coefficient based on results of lateral loading tests performed using large loading plate in the pit of a large-diameter deep pile.

Lateral Loading Tests in The Pit for a Large-Diameter Deep Pile

St. Louis, Missouri

Although the ground supporting the foundation can be regarded as three-dimensional nonlinear continuous body, in design, grounds are modeled as linear elastic springs. However, in reality, grounds exhibit nonlinear load-displacement (ρ-δ) characteristics. In Specifications for Highway Bridges (Japan Road Association, 1994), ground reaction coefficient is defined as the secant slope of noticeable displacement and load intensity on ρ-δ curve corrected according to width of foundation. For the purpose of examining the scale effect of large-diameter pile, this paper presents a study on scale effect of lateral ground reaction coefficient based on results of lateral loading tests performed using large loading plate in the pit of a large-diameter deep pile.
