| Abstract: | Bonding prestressed concrete and unbonded one with post-tensioning method have commons and differences during the construction condition. And the differences between the two projects can be embodied by construction process, prestressed steel paving, prestressed tension and pore canal grouting. Finally, the requirements for the construction management are summarized in the paper. |
