Abstract: The quality of compaction is crucial to high-filling. Dynamic compaction is a most widely used method for ground treatment. In the paper, experimental test for broken stone treatment by dynamic compaction is studied. Firstly, the properties of the filling of broken stones are analyzed. Secondly, the dynamic compaction test, the dry density test, and the particle-size distribution test are tried out. Thus, the reasonable working parameters and working techniques are defined. Lastly, based on the load-settlement test, the result of the stabilization is well acquired in according with work parameters.
