摘要
伸缩缝是为了满足材料结构变形要求而在结构中设置的间隙。它允许桥梁的变形在一定范围内变化，能提高桥梁的承载能力，而桥梁伸缩缝施工安装质量的好坏，直接影响到其使用寿命及路面的平整度。因此，要严格按照正确的伸缩缝施工工艺及质量要求进行施工。
The expansion joint is structural gaps designed to meet the requirements of material structure deformation. In alows a bridge to deform in a certain range, so it can improve the capacity of the bridge. The instalation quality of the bridge expansion joint directly affects the service life and roughness of road surface. Therefore, builders should act strictly in acco- rdance with the correct expansion joint construction technolo- gy and quality requirements for construction.
