| Abstract: | Considering the elastic compressive deformation of foundation pile with changes in cross section,the characteristics of soil around pile and soil resistance at pile tip,influencing coefficient of compressive stiffness is put forward with respect to pile length and pile tip resistance.The calculation formula of compressive stiffness is derived by using the variational principle.The calculation results agree with the test results in practice. |
| Keywords: | foundation pile compressive stiffness variational principle |
