Static pile load tests were conducted on the two piles which comprised group pile installed in sand and the test results were compared with those obtained from load transfer method. Predicted load bearing capacity of the pile which locates center portion of the group pile was less than that from the load test and the reason is thought to be the densification of the soil due to the installation of the group pile. Predicted pile capacity of the API method, Coyle and Sulaiman method were 77%, 90% of the bearing capacity obtained from the load test, respectively. Comparing ultimate bearing capacities of the pile locating at the edge of the group pile, those predicted by the API method, Coyle and Sulaiman method were 1.1 times, 1.3 times of the bearing capacity obtained from the pile load test, respectively.
