Abstract

The high-filled subgrade can be compacted by dynamic compaction and the lateral deformation can be limited effectively by reinforced soil, both methods can strengthen the stability of subgrade, but they will restrict each other when the two methods are used in the same project. It shows that reinforced soil can limit the function of dynamic compaction, on the contrary, the broad dynamic compaction energy can easily lead to fracture failure of reinforced plastic materials. To solve the problem of how to balance and optimize the parameters of dynamic compaction and reinforcement, the paper studied it combined model experiment. According to change the embedding depth of reinforced materials, the conclusions are drawn that the ratio of the effective reinforcement depth and the crater depth is exponential grows relationship with the embedment ratio, it is concluded that the single factor calculation formula for estimating the effective reinforced depth.
