| Abstract: |
The piers no.19~21 of the main bridge of China-Maldives Friendship Bridge are V-shaped piers, which are constructed by the method of "cast-in-place slant legs with cable-stayed connection and hanging section + cast-in-place block no.0 with inner supports". Based on the analysis of the whole construction stage of the bridge by the finite element method, the factors of concrete cracking during the construction of V-shaped piers are grasped. In view of the risk of structural cracks, the scheme of setting prestressed steel beam in the slant legs and accurately controlling the removal time of the cable hanging bracket is adopted to effectively prevent the concrete cracking during the construction of V-shaped piers. |
