Abstract
The development in construction field has increased with high rate in the last decades; many modern ways are started to be used to make the construction process easier than before. This thesis is focusing on tw
methods of construction in geotechnical field and they are pile driving and dynamic compaction. Both techniques produce high magnitude of vibration through soil due to the large amount of energy which is used in driving or compaction. Vibrations are generated in large values and propagate quite fast and affect many wide areas around the vibration source. Those vibrations may have a very destructive effect on the adjacent structures and the heritage buildings or even the underground
facilities. The damage occurs due to two reasons, soil settlement beneath foundation or the directly vibrations on the building. PPV(peak particle velocity) is considered the main indicator for the possible damage which may happens to the structures,therefore, a lot of parameters and their effect on PPV are studied in this thesis.Soil settlement is a very dangerous problem facing engineers when they have a vibration source such as pile driving or dynamic
compaction , the available models for evaluating settlement values due
to vibrations are also investigated.
