Abstract

Penetration tests were performed for two types of steel sheet piles which were driven in clay deposit and sand deposit. Penetration velocity data acquired from penetration tests were used in order to estimate bearing capacity and vibro-driveability of steel sheet piles. Bearing capacity values predicted from Davisson method and Bombard method were greater than that calculated from static bearing capacity formula by 11.9 times and 1.6 times respectively. Vibro-driveability predictions from $T\ddot{u}nkers$ method and ${\beta}$ method show correspondence to field test result fur sand deposit but not for clay deposit. From motor powers estimated by Savinov and Luskin method it can be seen that larger capacities of motor powers are required for clay deposit and adequate hammer was used for sand deposit.
