A new steel sheet pile of wide hat-type was developed. Advantage of using wide type of sheet pile is reducing steel weight and consequently cutting down construction cost. Field driveability tests were conducted in order to verifying vibro-driveability of wide hat-type sheet pile. As a result of the tests, penetration rates of newly developed sheet piles were less than those of U-type sheet piles. Axial stresses developed in sheet pile during driving were fur less than yield stress of sheet pile. Futhermore, initial penetration rates of sheet piles were much larger than those obtained from WEAP program.

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.
