| 摘 要： | 通过对桩基施工过程中实测资料的分析,探讨了沉桩时单桩周围土中产生的侧压力增量的大小、分布规律及影响范围,并与理论解进行对比。也将同一场地测得的侧压力增量与超孔隙水压力进行比较,并对桩端下土压力增量的最大影响半径进行了讨论。

| Abstract: | By analyses of the results measured during construction of pile foundation,we have studied the quantity,distribution and range of the increment of lateral pressure in soil around the pile caused by installation of pile,and compared them with theoretical estimates.The excess pore pressure measured in the same site is also compared with them.The maximum influence radius of the increment of soil pressure under the pile tip is discussed too. |

| Keywords: | pile increment of lateral pressure measured result theory of expansion of cavity |
