Applied Research on Dynamic Replacement Method in Tailings Residue Subgrade Reinforcement

摘要

Based on the reinforcing mechanism of dynamic replacement method, this article put forward the construction parameters and measures of dynamic replacement method, combining with the result of actual engineering field testing experiment. The field load test, standard penetration test and pore water pressure test results show that the characteristic value of subgrade bearing capacity is more than 130 kpa when the tailings residue subgrade has been managed with dynamic replacement method, providing references for applied research on dynamic replacement method in tailings residue subgrade reinforcement.
