Aiming at the complexity of the backfilling of the Yangshan Phase IV land area and the high requirements for the use of automated storage yards,a comprehensive construction method for vibro-compaction,dynamic compaction,and vibration rolling compaction was proposed for the reinforcement of the backfill layer,and a test was conducted.Through the test the technical parameters and construction technology of the ground reinforcement method were determined,a vibration monitoring system was developed and the influence of dynamic compaction on the bearing platform was monitored.The test results show that the settlement of vibration foundation can reach 90.6 cm,the settlement of dynamic foundation can reach 59.1 cm,and the impact of dynamic compaction method on the vibration and settlement of the platform is within the safe range.After static & dynamic penetration and compaction,the reinforced foundation can meet the design requirements and can provide comprehensive foundation for the subsequent ground reinforcement.
