Abstract

Ground anchor should not be used in soft clay, because anchor resistance can not be guaranteed. However, there is a way to increase the capacity of anchors. The anchor is an underreamed anchor by using high voltage electric discharge energy. In this study, a series of field test were carried out in order to find ultimate load of underreamed anchors in weathered soil at the new apartment construction site located in Inchon, Korea. Data were analyzed in order to define a relation between ultimate load and the number of electric discharge.
