| 摘 要： | 系统的对施工过程中超静孔隙水压力的产生、消散过程及其对地基土渗流场、地基应力场、桩体、桩间土与周围建筑物产生不同的影响做了系统分析,进而对桩顶冒水现象进行了解释,得出桩顶冒水现象是孔隙水在超孔隙水压力作用下通过冒水通道上升至地面这一结论。

| Abstract: | The produce and the vanish of the excess pore water pressure in the construction process, and the excess pore water pressure impacted on the seepage field of the foundation, the stress field of the foundation, the pile shaft, the earth among pile and surrounding buildings is system- atic analyzed, at last the phenomenon of the water-emitting from the top of static compaction pile was explained in this paper, the reason is the pore water rising to the ground from the pore channel by the excess pore water pressure. |

| Keywords: | static compaction pile excess pore water pressure seepage field stress field of the foundation |
