Perimeter Load Transfer in Drilled Shafts in the Eagle Ford Formation

Document Type: Proceeding Paper

Part of: Design and Performance of Deep Foundations: Piles and Piers in Soil and Soft Rock

Abstract:

Results of six full-scale compression loading tests at four sites in the Dallas area are considered. Compressive strengths (q_c) of the rock varied considerably (in the range of 0.75 - 3 MPa). A decreasing ratio of maximum unit perimeter load transfer (f_max) to q_c, although the ratios were much lower than those for the Melbourne Mudstone at all vales of q_c. A complex combination of borehole roughness, shearing strength of the parent material and degradation of the soft rock to soil during drilling (termed 'smear') contribute to the values of the ratio.
