【Abstract】 Based on finite element method analytical results and laboratory results conducted to determine bearing capacity of rectangular foundations on multiple layer geogrid reinforced sand. It can be concluded that bearing capacity of reinforced sand increases significantly. The effects of the depth to the first layer of reinforcement, vertical spacing of reinforcement layers, number of reinforcement layers, the size of reinforcement on bearing capacity of geogrid reinforced sand are investigated. The optimum geometric parameters of reinforced foundation are obtained. The results are very important for geogrid reinforced earth structural design and construction.更多还原
