The results showed as followed :( 1 ) The most important factor of atmospheric general circulation controlled and influenced the immigration of WBPH's populations was the patterns and the tempo-spatial changes of potential height field on 850hPa isobaric surface,(2) There were relative coincident air streams with a northern exposure on 850hPa isobaric surface during the migrations northward of WBPH and there were concurrent airflows with a southern exposure on 925hPa isobaric surface during the migration southward.

The results show that, with the expansion cone angle remaining unchanged, the sizing length of expansion cone does not have much effect on the residual stress of casing after expansion, but it has much effect on the expansion force required by tube expansion. The expansion cone angle has no effect on the maximum residual stress of casing, but it has remarkable effect on expansion force. When the radial component force of expansion force is greater than the material's tensile strength, the damage to the material will arise.
研究结果表明,在膨胀锥锥角保持不变的情况下,膨胀锥定径长对膨胀后套管的残余应力没有太大影响,但对套管膨胀所需要的膨胀力有较大影响;膨胀锥锥角对套管最大残余应力没有影响,但对膨胀力的影响十分明显,当膨胀力的径向分力大于材料的抗拉强度时,材料将发生破坏。

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.
