| 摘 要： | 对地面堆载作用下桩土系统的相互作用进行离散颗粒流模拟,分析端承桩在桩周土受柔性分布载荷作用下,桩侧负摩阻力的发展变化趋势,为负摩阻力的研究提供新的方法.数值试验结果表明,负摩阻力的分布随着地表荷载的增加而不断地发生变化,并且当达极限摩阻力后,其值随着桩身位置的不同有不同程度的降低,并非保持不变. |

| Abstract: | The soil-pile interaction under the action of ground stack load was simulated with discrete particle flow.The trend of propagation and variation of side negative skin friction on the end-bearing pile subjected to flexible distributed load of surrounding soil was analyzed to provide a new method for investigation of the negative friction resistance.Numerical test result showed that the distribution of negative skin friction varied continually with the increase in the ground stack load.The negative skin friction would decrease to a certain extent when its value reached limited skin friction instead of keeping unchanged. |
| Keywords: | particle flow negative skin friction ground stack loading pile ground |
