Experimental Analysis of the Behaviour of Piled Raft Foundations in Loose Sand

This paper presents the experimental analysis that was conducted on small-scale 1g physical models of piled raft foundation structures with a group 2 × piles in loose sand. The purpose to reduce settlement raft. test program included twelve experiments, three which were alone and nine rafts at pile distances 3d, 4d, 5d lengths 10d, 20d, 40d, where d is diameter. results show current conventional approach design foundations, high safety load factor assume take whole external applied load, very conservative. Instead, it more economical apply low bearing capacity for as reducers maximize use carry part load.
