RC连续曲线箱梁桥温度裂缝成因及控制措施

The cause of thermal crack and control measures of RC continuous curved box girder bridge

针对钢筋混凝土连续曲线箱形梁桥易出现裂缝这一现象,重点从温度裂缝着手,分析了温度裂缝的成因及特点,并结合实际工程提出了一定的控制措施,对控制和预防此类桥型温度裂缝的产生提供了依据。

To count the phenomenon that RC continuous curved box girder bridge tends to crack, the cause analysis and features of temperature crack is discussed in the paper from view of it and control measures are suggested on the basis of an actual engineering. Which has provided a foundation for controlling and prevention against temperature crack in this type of bridge.
