In this paper, the results of an experimental programme carried out on model pile groups have been reported. Lateral load tests were carried out on instrumented model aluminum pipe piles embedded in a marine clay at embedment depth ratios of 20, 30 and 40. Two pile and three pile groups were arranged in series and parallel configurations with varied spacing between the piles. The test results reveal that the capacities increase with spacing between the piles up to a certain value. Further there is an improvement in lateral capacities with increase in the embedment. Bending moments measured along the length of the piles indicate higher values for the rear piles. These test results obtained are found to be fairly in good agreement with the published results.
