| Abstract: | Based on the finite element numerical method,bowlas method is improved by employing the load transfer function of pile shaft soil about analysis of prestressed pipe-pile and soil interaction mechanism. This method avoids the limitation of field measurement. The Fortran is used to build the calculation program for the prestressed single pipe-pile and the computational results in various soils agree well with the compressive static load test results. It is reasonable to employ the calculation program to research the behavior of the pre- stressed pipe-pile. The results will be helpful for engineering application and further research about the bearing capacity behavior of the prestressed pipe-pile. |
