Abstract

A calculation method is presented to predict the drivability of vibratory driven piles and sheet-piles. The calculation model incorporates degradation of the soil resistance under cyclic loading. The model is strengthened by an exhaustive preliminary site measurement campaign which gave an insight in the dynamic behaviour of both the vibrated sheet-pile and the surrounding soil. The paper shows the correlation between measured and calculated driving times for several sites. 1. Introduction In order to install sheet-piles, three basic different driving techniques can be distinguished : impact hammering, vibratory driving and pressing. With regard to drivability, impact driving and pressing of piles is considered possible as long as the driving force - limited to a certain extent by available energ
