Abstract

Construction sources of vibration such as pile driving and dynamic compaction can produce earthborn vibrations problems for the supporting soils. The process of pile installation can have a significant influence on the surrounding ground. Vibrations create the stress waves traveling outward from the source through the soil and cause damage due to dynamic vibration induced settlement. The objective of the present paper is to study the vibration effect through both pile driving and dynamic compaction technique on the surrounding soil, by monitoring peak particle velocity (PPV) which can be a sign for the expected damage. PPV consider the most concern parameter to express the vibration hazard, therefore PPV is investigated at different soil stiffnesses, rammer weights, and pile lengths. A series of Axisymmetric finite element analysis using Plaxis 8.2 dynamic module are run to simulate processes of both a single pile installation using driving technique (hammer type) and dynamic compaction. By measuring Peak Particle Velocity (PPV) with different pile lengths, it is noticed that the vibration is generated at the pile toe then transferred conically from the pile to the soil. It is illustrated that by increasing soil stiffness the PPV increases. On the other hand the dynamic compaction has a great hazard on the surrounded soil due to the enlargement of the dropping weight of tamper which increases PPV. Increasing Hammer and damper weight for both pile driving and dynamic compaction increases PPV.
