Abstract
The geotechnical properties related to strength or rigidity of ground is very important in the design and construction of civil engineering structures. As a method to acquire the velocity of shear wave correlated with N-value and undrained shear strength, a new surface wave method which is applicable to the underwater ground was proposed. The results of on-site trials at seafloor indicated that the estimated S-wave velocity distribution tends to agree with the profiles of soil type and N-values obtained by drilling surveys and the standard penetration test. The proposed method is expected to be an effective tool for the geotechnical investigation of seabed, and to be an applicable for better design and construction.
