Construction-Induced Vibration Due to Pile Casing Driving
Ground vibration is generally caused by construction activities, e.g., pile driving, sheet pile driving, dynamic compaction of soil, blasting; natural activities, e.g., earthquake, landslide, etc. In urban region, construction-induced vibration is mainly caused by pile driving, sheet pile driving, etc. Pile driving induces vibration in the soil which is transmitted to neighbouring structures, thereby causing potential damage, such as unequal settlement of foundation and distortions or cracks within the building. In the present study, field observation has been conducted at two sites during pile casing driving by (i) Impact Hammer upto a depth of 28 m beneath the ground surface, (ii) Hydraulic Vibratory Hammer upto a depth of 10 m beneath the ground surface. A comparative study has been made between two sites based on the following observations. Peak particle velocity (ppv, mm/s) has been measured in the sites with varying distances from the pile driving location. Ground motion amplitude has also been acquired at different depths while driving pile casings. Based on the site observation, regression model has been created to predict the peak particle velocity. The model is very useful for predicting PPV for site-specific parameters. Thereafter, it has been compared with the existing ground vibration model obtained from field study.
