Vibratory pile driving has an advantage of reduced noise pollutions compared to impact pile driving and it has been very widely used in the installation of sheet piles. However, very little has been known about the driveability characteristics of sheet pile under vibratory driving. So, the proper sheet piles and vibratory hammer for an given soil profile and depth are determined on a empirical basis. In this study. the driveability of U-type sheet piles are analytically estimated using the commercial WEAP(Wave Equation Analysis of Piles) program. The WEAP analysis shows that penetration rate of sheet pile decreases as N value increases. And if penetration length is not over 20 meters, the rate of penetration decreases as the sectional area of sheet pile increases.
