From the viewpoint of CIM and initial defect in marine ground improvement, a way to obtain more detailed construction management information in addition to the conventional construction management information is required. In the present study, in order to examine the relationship shear wave velocity and shear strength of ground improvement soil as an approach to development of new quality management method of ground improvement based on Shallow seismic reflection profiles, made the ground improved specimens, conducted bender element test and the element test. In addition, we compared the shear strength estimated by various design equation based on N-value to shear strength of experiments, examined the applicability of design equation based on N-value. As a result, it was confirmed that shear wave velocity and shear strength have positive correlation. The shear strength estimated by various design equation based on N-value have large variation by design equation based on N-value was implied.
