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.

In the sub-cluster scale theory, R1 indicated the possibility which the hole skip the middle size hole to become a big cell, it would make striking influence on the tensibility ; R2·R1 indicated the well-distribution degree of cell size, it would make the notable influence on the cell density P; R2/R1 indicated the big cell and small cell exchange possibility, it would make the remarkable influence on the re-spring degree because of the different influence with the hole size.

其中R1表征泡孔越过中等泡向大泡孔缔合的倾向，它对断裂伸长率影响最大；R1·R2表征泡孔的均匀性，受泡孔密度影响较大；lnR2／R1表征体系在发泡过程中大小泡孔相互转化倾向比，由于大小泡孔对泡体回弹率贡献不同，lnR2／R1对发泡体回弹率影响较大。

To die together with the release铁盖burning furnace used in hot, brush with oil dip coated mold hole again, check铜壶will be followed by injection mold slurry surface hole (only half-filling holes), will die immediately give onwards, slowly turning to face sticky paste evenly in the hole wall, and then on the furnace will be inserted into holes in the bamboo pulp surface scraping the walls of the hole.

The stress distribution on the cross section of geotextile with a circle or an ellipse or a square hole under uniaxial tension or double-axial tension was calculated with boundary element method program. The results show that the stress concentration appear at the range from the hole side to about 3 times of the hole diameter, and the degree of stress concentration near the hole is related to the shape of the hole, the size of the hole, the position of the hole and the dimension of the specimen.
