| 摘 要： | 桩端沉降测量和试桩资料的分析结果表明,桩在传递上部荷载与地基土之间产生的应力应变过程,表现为桩的弹性杆件和地基土的弹—塑性变形特征。从而对受荷桩,尤其是长柱和超长桩的应力应变特征有了更切合实际的认识。

| Abstract: | The analysis of pile tip settlement measuring and the data of pile testing,has ex-pressed that the stress-strain process of upper loads on pile shaft and foundation soil has elastic deformation characteristics of both pile and foundation soil.So,for loading pile,especially long piles and ultralong piles,their stress-strain characteristics have been known exactly. |

| Keywords: | pile tip settlement deformation ultimate state residual stress residual strain |
