Discuss on Dynamic Compaction Treatment on Rubble Foundation in Coastal Road of Nuclear Power Plant

When deal with the coastal silt foundation, according to the geologic and actual condition of the project, dynamic consolidation method on rubble foundation is qualified as practical. After dynamic compaction,the result of roadbed load test, drilled core test and settlement observation showed that the bearing capacity and settlement control of the roadbed can meet the design requirements. The result of the treatment is good. For dynamic dompaction is simple in equipment usage, convenient in construction and economical, it can be widely used in coastal silt riprapped foundation treatment.
