分析了在桩头作用谐和荷载时有限长桩与无限长桩的动力反应 ,并进行了对比 .分析表明 ,在一般情况下 ,当桩长径比 l/ d≥ 1 0时将有限长桩作为无限长桩来分析 ,所得内力与位移最大值误差在工程允许范围内
The dynamic response of the finite pile and the infinite pile is analyzed when the pile head acts under harmonic load. The analysis shows that under the condition of l / d≥10, As an infinite pile to analyze, the maximum internal force and displacement error within the project allowable range
