Abstract:

Considering a vibrating pile hammer, a pile and the soil conditions, the mechanism of influences of high frequency vibration pile construction on surrounding environment were analyzed. A three-dimensional finite element model of vibratory piling was established to reproduce the pile-driving process. Having confirmed validity of the model, variable parameters were investigated. The study showed that influences on the surrounding environment decrease with the frequency of pile hammer, and increase with static load of pile hammer and pile diameter. A sandy soil field was more easily affected by vibratory pile driving as compared to a clay soil field. Moreover, the harder the soil, the more serious environmental impact would be. To reduce the effects of pile construction, measures should be taken based on the analysis.
