The results show that the sturcture of each of Tin clusters is obtained by capping one Ti atom to the Tin-1. The Natural bond orbital analysis show that the 4s , 4p, 4d orbitals hybridizes with 3d orbital, and about one electron transfer from 4s orbital to 3d orbital. Moreover, the electrons also transfer between different atom. The results also indicate that the average bond length of clusters were determined by the 4d and 3d orbitals except Ti7. But for Ti7, the average bond length only depend on 3d orbital.

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.
