对某跨海斜拉桥桥面线形、索力进行了检测与评价,并与交工资料进行了对比分析,其结果表明:桥面线型较为平顺,上、下游对称性较好;索力变化幅度不大,分布较为均匀,且上下游两侧实测索力比较对称,均小于设计索力值;运营状态下桥梁结构相对于设计状态,具有较好的整体工作性能。
The paper analyzes and evaluates the line shape and the cable force of a bridge across the cable-stayed bridge, and makes a comparative analysis with the traffic data. The results show that the deck shape of the deck is relatively smooth, the symmetry of the deck is good, The magnitude is not large, the distribution is more uniform, and the measured cable forces on both sides of the upstream and downstream are more symmetrical, which are less than the designed cable force. Under the condition of operation, the bridge structure has good overall performance compared with the design state.
