Abstract:The weathered sand is weathered from the granite in the San GOrge. Because of the different weathered degrees and the unstable particulate grade, it belongs to a kind of inhomogeneous material. The mathematical model for its maximum dry unit weight ρd max and the content ρ5 of coarse particle is established through the compacting test on the weathered sand. The figure of the three-factors, namely, compactnessd D, in-situ dry density ρd and content ρ5 of coarse particle is given. Through the engineering application in the past three years the good result has been obtained.
