Dynamic Ground Response during Vibratory Sheet Pile Driving
Vibratory sheet pile driving is a widely used foundation method. In order to investigate the effect of different operational parameters, such as vibration frequency and eccentric moment on sheet pile to ground interaction, carefully monitored and documented field tests were performed. A single sheet pile was vibrated into a sandy soil deposit (esker) and different operational parameters were varied. The interaction between the vertically oscillating sheet pile and the surrounding ground was studied, using sensors on the vibrator and on the ground in the vicinity of the sheet pile. The effect of vibration frequency and eccentric moment on sheet pile penetration speed and emitted ground vibrations is presented. When the sheet pile is vibrated at the resonance frequency of the vibrator–sheet pile–soil system (system resonance), ground vibrations increase significantly and sheet pile penetration speed decreases. It is concluded that the vibration frequency is an important parameter for the efficient and environmentally safe installation of sheet piles. These tests provide insight into the interaction of a vibrated sheet pile and the surrounding ground. Based on these results, guidelines for the efficient and environmentally friendly installation of piles and sheet piles are proposed.
