The flat dilatometer test(DMT) is a useful geotechnical tool for estimating in-situ properties of various types of ground materials and the application of flat DMT is increasing. The existing relationships which are used to estimate the design parameters of soft deposit depend on the regional geotechnical characteristics and then it is necessary to investigate the applicability of the flat dilatometer in Korea. In this paper, the flat DMT has been conducted in soft marine deposits. The results estimated by existing relationships and those obtained from laboratory tests were compared. Based on the results, some factors influencing the relationships were examined and adjustment of empirical expression was performed.
