A convenient means of the determination of the soil properties would be to correlate it with the result of field test such as the cone penetration. But It is difficult to correct evaluation for the soil properties by the only one test at the reclaimed coastal region. In this study, the cone penentration test and seismic wave exploration are performed at the reclamed coastal regione which has the soil layers to be analyzed and the dynamic soil properties. The results obtained from this study were summarized as follows; 1) As a result of field test, the study area was found to be 3 layers. 1st layer was filled in the ground to the depth of 2∼3m and the next layer was showed the soft clay layer to 40∼45m from reclaimed layer. 3rd layer proved to be a bedrock. 2) When the cone penetration test, the cone resistance was observed very great value in the ground to the depth of 0.7m due to the result of ground compaction with the traffic load and consolidation in the nature etc. 3) As the result of study, it presented that the correlation between the cone resistance and the seismic wave velocity is distributed the only a certain range with a group. The correlation between the cone resistance and the seismic wave velocity is determined through the regression analysis. The correlation is assumed a line relationship between the cone penetration resistance and the seismic wave velocity. 4) The method of using the empirical correlations between the cone penetration test and seismic wave exploration is an effective method by which the soil properties can be decided simply. This method has limitations in application because its research and application is in the early stage. In considering the proper engineering factors, however, it can be used efficiently in ground investigation and design.
