群杭の水平抵抗に関する模型実験 (2)

Abstract

Lateral load tests are carried out on model free-headed pile groups. Pile details and ar-rangement of pile groups are shown in Fig.2. Thc test piles are embedded in relatively densesand made by means of boiling procedure. The variations of group efficiency with pile spacingfor Box-pile groups are shown in Fig.7. Some comparisons are made between the test resultsand theoretical predictions based on the method developed by M. F. Randolph (1981). The pre-dicted and measured values of group efficiency are generally in good agreement, with the maxi-mum discrepancy being about 30 % (see Fig.8).
