• Abstract:
  Lateral loads on drilled shafts are often the controlling factor in their design. These lateral loads are transferred to the surrounding soil or rock, and estimation of the capacity of the shaft to resist lateral loads is a critical part of the design. The lateral load-deformation relationship of a drilled shaft and its supporting soil is commonly modeled using the p-y curve method. P-Y curves vary with soil type, deposition characteristics and depth, but general curves have been developed to represent common soils. Unfortunately, no p-y curves have been developed to represent the behavior of loess, cemented silt that is common throughout much of Kansas. This lack of available p-y relationships has meant that less applicable curves, normally those for sandy soils, must be used.
