Book excerpt: A series of full-scale lateral loading tests for instrumented piles in cohesive and cohesionless soils were carried out at Oregon State University to assess the lateral response of piles in freefield and near slope conditions. Instrumentation data from the free-field piles and the piles installed at different distances from the slope crest were used extensively to monitor lateral pile response and to back-calculate p-y curves. For the cohesive soil tests, it was found that for small pile head displacements (less than 1.0 inch), the proximity of slope has insignificant effects on piles 2D or further from the slope crest where D is the pile diameter. For the piles on the slope crest, the effects of the soil slope should always be considered. The presence of the slope has insignificant effects for piles installed at distances of 8D or greater from the crest. For the cohesionless soil tests, the effects of slope on lateral pile capacity are insignificant at displacements of less than 2.0 inches for piles located 2D and further from the crest. For piles located at 4D or greater from the slope crest, the effects of slope on p-y curves are insignificant.
