Dynamic compaction is one kind of foundation treatment method normally seen, and dynamic compaction will cause vibration wave to surrounding soil body to affect buildings in certain scope in soil body with different degrees. In order to improve effectiveness for geotechnical engineering analysis for underground tunnel foundation and foundation suitability analysis, dynamic compaction treatment method for foundation was adopted, and influence of dynamic compaction on pit tunnel in construction area was analyzed. Three-dimensional ANSYS/LS—DYNA finite element software was applied to stimulate tunnel vibration and stress and to review bearing capacity and crack width of tunnel structure.
