Abstract: To characterize the coarse-grained soil of the fillers in Zhijiang North station of Shanghai-Kunming Passenger Dedicated Line, the vibration compaction test was conducted to study maximum dry densities under different granular compositions. Considering the non-linear relations between granular compositions and maximum dry densities, a BP neural network prediction model of which the input layer was consisted of granular compositions, grading index and fractal index was established based on the backwards error p…
