摘要
研究了桩柱在重锤冲击下的理论计算.建立了重锤对桩柱冲击的动力方程,利用桩柱顶位移对时间导数,与桩柱顶位移对位置导数的关系,推导出了重锤对桩柱顶的冲击力公式.算例分析表明,该方法对计算冲击荷载具有较高的精度.
Abstract
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.
