| 摘 要： | 在饱和软土小孔扩张理论的基础上,推导了一般粘性土的弹塑性解主要包括弹性区、塑性区任一点的应力增量、塑性区边界上径向位移、塑性区半径及桩土间的挤压应力,通过现场测试分析了打桩对周围土体特性的影响,并给出了其扰动区域。

| Abstract: | On the basis of saturated soil hole expansion theory,the author derivates that elastic plastic solution of common clay is containing elastic range,the increasement of arbitrary point in plastic range,radial displacement on the boundary of plastic range,radius of elastic range,and extrusion stress between pile and soil,analyzes the influences of piling on surrounding soil's characteristics through field detection,and gives its disturbing regions. |

| Keywords: | pile extrusion stress small hole expansion theory |
