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。
