Workshop 2

Evaluation of Pile Nominal Resistance from CPT Data

Theme

The cone and piezocone penetration tests (CPT and PCPT) are considered one of the most useful in situ testing for subsurface soil investigation. The tests are simple, fast, reliable, and economical tests that can provide continuous soundings of subsurface soil with depth. The CPT/PCPT measurements (qc, fs, u1 or u2) can be effectively used for soil identification and classification, and for the evaluation of different soil properties. Due to similarity between the cone and the pile, the CPT/PCPT data has been effectively used to estimate pile resistance. Several direct CPT methods have been proposed to estimate the nominal resistance of piles (total, tip and side) utilizing the CPT and CPTu data (e.g., Schmertmann 1978, de Ruiter, and Beringen 1979, Bustamante and Gianeeselli 1982, Eslami and Fellenius 1996, Almeida et al. 1996, Powell et al. 2001, Bloomquist et al. 2007, Lehane et al. 2013). This workshop is planned to provide the participant with an understanding of the cone and piezocone penetration tests (CPT and PCPT), present the different methods/approaches for estimating pile reissuance from CPT/PCPT data, and introduce available Pile-CPT design softwares. Each design method will be introduced with a discussion of how to assess the end bearing and side resistance separately. A set of worked examples will be presented to the participants for pile load tests in different soil conditions.
