| | Abstract | | Passive surface wave method is the one of the effective ways to investigate S-wave velocity structure. Coventional passive surface wave method is mainly used for 1D investigation, and is rarely applied for 2D or 3D surveys. This paper shows a case study of the 3D survey for S-wave velocity structurby the passsive surface wave method obtained by many sensors deployed on a circumference at an inside the test circuit road. |
