Abstract: Combining the dynamic consolidation of a nuclear power plant foundation, varieties of in-situ tests are used to monitor the vibration intensity and safety of cutoff wall under dynamic compaction. Through experimental research, dynamic compaction parameters which ensure the cutoff wall safety and the dynamic compaction effect are analyzed; the controlling standard for long-term dynamic compaction is given. The long-term monitoring results show that the adopted monitoring scheme is reliable and efficient so as to provide a very important reference for the similar projects? safety assessment.

Key words: dynamic compaction, vibration, cutoff wall, environmental impact, safety assessment
