Abstract
The influence of surrounding soil on low strain integrity test of piles is still not precisely quantified. This had led to difficulties in assessment of integrity of piles embedded in soils that produce damping effects on the tested piles. Theoretical model, which incorporates soil effect on wave propagation in pile body, was formulated using numerical analysis. This model was produced based on friction-displacement correlation. The proposed model assuming pile cast in very dense granular soil was compared with PIT-S software, which simulates propagation of low strain waves in piles. Generally, the Force-Velocity curves generated using PIT-S software and this model was found to be similar for pile subjected to short duration light impact. However, these similarities in results were found to be time and depth dependent.
