The construction of dynamic consolidation method was carried out on the gravel soil backfill foundation of a substation.During the process of dynamic consolidation,the amount of compaction subsidence and ground uplift at each point were observed and recorded.A detail analysis was conducted on the settlement of the ramming pit and the uplift deformation characteristics of the soil around the compaction pit,and the effective compaction coefficient was calculated.Additionally,the impact of the construction,such as vibration and side extrusion was also observed on the surrounding environment and engineering,and the minimum safe distance for construction with surrounding engineering was determined.A series of tests,such as shallow plate loading test,Rayleigh wave test,and dynamic sounding test,were carried out to determine whether the effective reinforcement depth,bearing capacity,and deformation indicator of the treated foundation meet the design requirements.The rationality and applicability of the dynamic consolidation method for the filed site use were evaluated,and construction parameters of large-scale dynamic consolidation reinforcement of gravel soil backfill foundation were proposed.
