| Abstract: | According to the wave theory, a computational model and the wave equation of pipe piles are established considering the effect of soil plug. A new method is proposed to calculate the effect of the soil plug, which can be used to analyze the state of motion of the pile and soil plug in the piling process at anytime. And then the corresponding program is compiled. By using this method to analyze the piling of practical engineering, the results show that the calculated values with the proposed method are consistent with the engineering measured data in determining the effect of soil plug and pile driving process prediction. |
