Key Technology of Construction for Middle Tower of Three-Tower and Two-Span Suspension Bridge

Abstract:

Tai-Zhou Bridge, which has a three-tower and two-span, is 1080 meters long and 2 meters wide. The middle tower is a huge caisson foundation and chevron steel tower structure. It is important to make some effective technical measures to control the processes of caisson foundation’s installation, such as floating, orientation, implantation and final sunk, especially in complex conditions. Eroding model tests for the caisson foundation’s floating phase and sunken phase play an important role in the prophase installation. Information control technology could exactly guidance the sunk of cession. Finally, the linkage control of steel tower’s manufacture and operation is necessary for the precision of installation.
