| Summary: | 碩士 === 國立海洋大學 === 河海工程學系 === 84 === Dynamic Consolidation is a fairly simple technique which
consists in delivering high energy impacts on to the ground
to be compacted in order to densify the compressible soil at
depth. It has been carried out on the test area of reclaimed
site in Mailiao, and has performed excellent results in all the
volume of soil treated. However, the interpretation of the
dynamic consolidation method and the availability of the
model developed should still be modified.
Based on the idea of Boussinesq stress increment together with
field data collected from the Mailiao soil improving site under
construction, the relationship between the dynamic
compaction energy and the degree and depth ofsoil improvement is
evaluated. It is found that the results computed from the model
developed in this study agree reasonably with field observations
and arebetter than those obtained from others proposed.
Key Words: soil improvement, dynamic consolidation method,
compaction energy, influence depth, influence
energy, CPT-qc。
