The simple vane shear test was also performed to obtain the undrained shear strength during penetration drilling. This research adopted a preparation method in the laboratory to simulate the sea bed soil. Using the vane shear method obtained the undrained shear strength of marine clay slit to assess the correlation of undrained shear strength between laboratory and in-situ soil. This study adopted extrapolation and regression method to evaluate the total mound need of breakwater based on the real mound count which was provided by a supervisor. On the other hand, combined with the Geo-Slope program in orderto simulate the settlement of marine clay silt, and also conjecture the amount of mound by back analysis. According to the results and analysis of experiment, it can be determined that seabed marine clay silt fit in with the definition
