Behavior of laterally loaded pile qroups is mainly influenced by the interaction between piles and the local yielding of soil existing near piles. In preceding two papers, the theory to predict the behavior of pile groups, which was considered under the above conditions, was proposed by the authors, and then the load and displacement relationships computed by the proposed theory were compared with the full scale pile test results (two piles arranged in series and parallel) in the field. As the results, the both results showed fairly good agreement. However, the examinations for the pile group efficiency and the stress which develop within piles have not been made. In this paper, the computed results for the above points based on the propsed theory are compared with the many model test results. As the results, the following conclusions were obtained : (1) The pile group efficiencies observed from model tests show fairly good agreement with the predicted ones based on the proposed theory. However, the computed values from the elastic theory, in which the soil yielding is not under consideration, depart greatly from the measured results. (2) The proposed theory can predict the distribution of bending moment and the imposed load of each pile in group fairly well.
