| description | Impact driving is one of the driving systems that applies a series of hammer
strikes to drive the sheet pile into the earth. There have been instances reported
where pile head is damaged due to the action of impact hammer. The pile head
failure causes the difficulty in pile driving. In industry, the pile head is designed
through trial-and-error method to reduce the damage. A systematic study with the
consideration of different parameters of pile head should be carried out to study the
stress distribution within pile head. This is to achieve the best and economical design
of pile head in minimizing the damage. LUSAS software is used to simulate the RC
sheet pile with the vertical impact load acting on its top. The first analysis is to
justify the maximum impact load from the impact of hammer ram based on different
approaches. The approaches of stress wave theory and the equation of motion
provide a more reasonable magnitude of maximum impact load compared to the
dynamic amplification factor. The second analysis is to determine the effect of
confinement ratio on stress distribution along the RC sheet pile. The result shows
that the effect on the trend of stress distribution is small. The third analysis is to
study the effect of geometry on stress in pile head of RC sheet pile under vertical
impact load. The result shows that there is no effect of geometry on stress in pile
head for the range of pile head parameters considered in this study. |
