| In this paper the factors developing ground disturbance with the penetration of PDB mandrels are analysed by using field reconnaissance and laboratory test. In the laboratory tests, the amount of smear zones around the PDB mandrels is compared with respect to the shape and the size of mandrels by penetrating model mandrels of various shapes into the reconstituted clay. The shapes of mandrels selected are circular, oval and rectangular. It was recognized from the field reconnaissance that the size and shape, driving techniques of mandrels, as well as the size and shape of anchor shoe could develop ground disturbance. The mandrels that would reduce the smear effect of clay is oval and rectangular shapes rat her than circular one. It was found that the smear effect becomes smaller as the ratio of the long and short edge of the rectangular shape mandrel becomes larger. |
