Vesic's solutions to cavity expansion that include cylindrical cavity expansion and spherical cavity expansion are introduced. Then cylindrical cavity expansion theory is applied to study compaction effect of pile driving in saturated soil. Based on the results of conventional triaxial tests, a trilinear curve model is used to simulate stress-strain curve of strain-softening materials. Meanwhile, trilinear curves are also used to simulate curves of volumetric strain, minor principal strain and major principal strain. By using elasto-plastic theory, analytical solutions to cylindrical cavity expansion in strain-softening soil are presented. According to the mechanism of statically pressed pile driving, compaction effect of pile tip can be viewed as hemispheric cavity expansion. Therefore spherical cavity expansion theory is applied to obtain the solutions to stress, strain, displacement fields and final pressure. Resistance force of pile tip is calculated to estimate static pressure.

对于小电流扩散态真空电弧,重点仿真分析不同电弧电流与不同纵向磁场对其关键特性的影响,部分仿真结果进行了实验验证;对离子处于超音速流动的收缩态真空电弧的仿真表明,真空电弧的磁收缩主要是由于霍尔效应引起的,离子温度和电子温度沿轴向先增大后减小,马鞍形分布的纵向磁场能够更有效地抑制真空电弧的收缩,而且阴极斑点分布对真空电弧特性也有着显著的影响;对离子处于亚音速流动状态的大电流真空电弧的仿真表明,部分等离子体不能到达阳极而损失,马鞍形分布的纵向磁场能够更有效地抑制电弧等离子体的损失,同时能使阳极电流密度和能流密度的分布更加均匀。

The load transfer and settlement behavior from the simulation results are also analyzed: most of the column load concentrates on the enlarged column cap, and distributes quickly, there is more load attenuation at the variable section. The skin friction of enlarged column cap develops more adequately than underside column. The column settlement concentrates on enlarged column cap, and soil settlement concentrates on a little area below the variable section.
