Abstract
As the land is very precious in urban areas and coastal regions, many structures are built in close proximity. When the soil is weak and heavy loads are to be carried, pile foundation is adopted for such structures. The impact caused by pile driving is a potential hazard to neighbourhood structures. Berthing structures are constructed using piles and the effect of pile driving on already installed adjacent piles is important. To predict the effect of pile driving on neighbourhood piles, measurement of ground and structural vibrations during prototype pile driving was carried out at a site in the city of Chennai, India. The soil at the site up to a depth of 19 m is mainly fine to medium sand. A driven cast in-situ pile of 600 mm diameter (D) was driven up to a depth of 15.8 m. The 25mm thick mild steel (M.S) tube casing is driven by 4.1t hammer with a drop height of 2.5m. During the pile driving, for every blow of hammer, the acceleration of the ground at various distances 5D, 8.33 D and 25 D from the pile are measured. Piezoelectric acceleration transducers, power amplifiers and taper recorder are used for measurement. The time history of vertical and horizontal ground accelerations as well as time history of vertical acceleration of an already installed pile at a distance of 6.25 m was analysed using PC based data acquisition systems. The time-histories and spectrum of ground and structural accelerations are presented.
