| The lateral load-deformation relationship of a drilled shaft and its interaction with supporting soil is modeled as a p-y curve. The soil-structure response of drilled shafts in loessial soils is often approximated by the family of sandy soil p-y curves.; The purpose of this research was to define the significant engineering properties of Kansas' loessial soils through a literature review, laboratory tests, and in situ tests and to determine the soil-structure response by performing full scale lateral load tests on six drilled shafts.; Laboratory testing was performed in accordance with American Standard of Testing Materials (ASTM) procedures. Shaft deflections were measured using inclinometer soundings and correlated with the CPT cone tip resistance (q c). A hyperbolic model was developed to correlate ultimate soil resistance (Puo) to the CPT cone tip resistance (qc) at any given depth and a family of p-y curves, unique to loess, was developed. |
