| | Abstract | | Dc is used for the execution management of an earth structure as a standard. Checking that all value of Dc measured in some predetermined spots of the earth structure is beyond a fixed permission management value evaluating the soundness of the earth structure. However, this method can not find out local weak points of the earth structure. Then, it is thought effective to use distribution of two-dimensional Vs by surface wave method. In this study, in order to examined influence which crush of soil grain has on modification, the strength property, and Vs, triaxial compression tests and the bender element tests were done. |
