群杭の水平抵抗に関する模型実験(1)

Abstract

Lateral load tests are made on model free-headed pile groups. Pile details and arrangementof pile groups are shown in Tables 1 and 2. The test piles are embedded in relatively dense sand ofDr~70%. The variations of group efficiency with pile spacing for Parallel-, Series- and Box-pilegroups are shown in Figs. 8-10. Some comparisons are made between the test results and theo-retical predictions based on the method developed by M. F. Randolph (1981). The predictedand measured values of group efficiency are generally in good agreement, with the maximum dis-crepancy being about 30% (see Fig. 11).
