摘要
研究及分析了大桥钢箱梁合拢段的温度变化特性 ,根据布设的监测系统和实测资料 ,研究了预留合拢间隔的变化规律及合拢端面的时空变化特性 ,探讨了合拢时段的选择 。
The variation characteristics about the closure section of the bridge's steel box girder caused by temperature are analyzed in this paper. On the basis of measuring system and the measured data analysis, the variation regulation of the reserved closure interval, the space-time variation characteristics of the closure section, and the closure time are discussed. It is effective to instruct the closure process of the steel box girder and has practical value.
