LATERAL LOAD TESTS ON DRILLED SHAFTS IN CEMENTED SOIL

摘要

Drilled shafts are used in many civil engineering projects including bridges, retaining walls, offshore structures, and tanks. Advantages of drilled shafts include the fact that the excavation can be readily inspected and the competency of the bearing material can be verified. The Arizona Department of Transportation (ADOT) makes extensive use of relatively large drilled shafts for foundation support of transportation structures. Because of this interest in drilled shaft behavior, ADOT has sponsored research on drilled shaft performance and the field load tests reported in this paper. Lateral load tests were performed on four 1.07 m (42 in) diameter drilled shafts at the 101 Freeway and Warner Road in Tempe, Arizona. Loads and deflections at the shaft top were measured and strain gages were used to ascertain the distribution of moments within the drilled shafts.
