Theoretical Calculation Analysis of Pile Column under Heavy Hammer Impact
The theoretical calculation of pile column under the impact of heavy hammer is studied.The dy-namic equation of the impact of the heavy hammer on the pile column is established.Based on the relationship be-tween the derivative of the displacement of the top of the pile column with respect to time and the derivative with re-spect to position,the equation of the impact force of the heavy hammer on the top of the pile column is derived.The calculation results show that the new method has high accuracy in calculating impact load.
