饱和粘土中单桩沉桩引起的超孔隙水压力分析

Analysis of excess pore water pressure during single pile driving in saturated soft soil

以圆柱孔扩张理论为基础,通过实测资料的分析,探讨了沉桩时单桩周围土中产生的超孔隙水压力的大小、分布及影响范围,得出了单桩沉桩后土体中沿径向及深度方向的超静孔隙水压力规律,并与理论解进行了对比。

By comparing the field measurements, the mechanism of lateral and deepness direction of the excess pore pressure during penetration is discussed in this paper,which is based on cavity expansion method. The comparisons of the theoretic result are also carried out.
