| 摘 要： | 伸缩缝是桥梁构造中的重要组成部分,它对公路车道的平整度影响较大,而且会对桥梁的整体结构和安全产生很大的冲击。为了改善这一现象,一方面应当加大桥梁的联孔长度以减少伸缩缝的数量,另一方面要不断改进伸缩缝的形式、材料以及设计和施工质量。目前,桥梁伸缩缝问题仍处于探索研究中。

| Abstract: | Construction of bridge expansion joints is an important part of,Flatness of its lane road greater impact on the overall structure of the bridge and would have a huge impact and safety.To improve this phenomenon,one should increase the length of the bridge joint hole to reduce the number of expansion joints,expansion joints on the other hand must constantly improve the form,materials and design and construction quality.Currently,the bridge expansion joint is still in the exploration and research in the probl... |
