| 摘 要： | 疏桩基础是近年来开始的对桩基设计理论的新探索。它以控制建筑物的沉降量和补偿天然地基承载力不足来确定桩的补偿量，因此它的变形性状有别于传统的桩基。选用了能描述土体塑性特点的弹塑性本构模型，利用研制的并经过算例验证的三维有限元程序对疏桩基础的变形性状进行了分析，得出了疏桩基础的整体沉降、桩间土体的压缩、桩端下土体的压缩等的变化规律。 |
| 关 键 词： | 疏桩基础 变形性状 三维有限元法 建筑物 整体沉降 桩距 |

| Abstract: | Scattered piled foundation is a new exploration of pile foundation design theory.It determines the pile compensation according to the controlling settlement and deficiency of bearing capacity of foundation, so its settlement capacity is difference with that of traditional pile foundation. The elastic-plastic constitutive model has been employed in order to consider the plasticity of soils.By verified 3D-FEM program on the settlement characters of scattered pile foundation, the changing laws of the scattered pile foundation settlements, soil settlements between piles and soil settlements under the bottom of piles have been drawn. |
| Keywords: | scattered pile foundation settlement capacity 3D-FEM |
