ABSTRACT

The presentation here is limited to the testing of single, full-sized piles but acknowledgment is made that numerous investigators have obtained valuable results from testing model piles in the laboratory. For example, Chapter 5 details the contributions of several workers who provided data that allowed numerical values to be assigned to the effects of pile-soil-pile interaction. In regard to pile groups under lateral loading, the work in the laboratory of Franke (1988), Prakash (1962), and Shibata, et al. (1989) is worthy of note. The centrifuge has become a popular tool for the investigation of problems in soil-

structure interaction and is used by many agencies in many countries. The centrifuge has been used to investigate the problem of single piles and groups of piles under lateral loading. Among the investigators who have used the centrifuge to study the response of piles to lateral loading are Kotthaus & Jessberger (1994), Terashi, et al. (1989). Bouafia & Garnier (1991), and McVay, et al. (1998). The results of centrifuge tests have provided useful information, particularly with respect to groups of piles, and the technique is expected to continue to contribute to the understanding of piles under lateral loading.
