| 摘 要： | 通过影响混凝土体变因素的分析，推导出桥面连续的一联长度计算公式．在保持桥面平整顺畅及行车舒适的前提下，合理确定伸缩缝宽度；改变传统的伸缩缝结构位置，将其从原桥梁端部移至距梁端60 cm处，称之为“桥面滑动伸缩缝”．

| Abstract: | Based on the analysis of concrete alternation elements, this article deduces a calculation formula about the continuous deck length. The width of the expansion joint is reasonably defined provided that the deck is flat for a comfortable and ease movement. The expansion is specified in a position, 60 cm away from the bridge beam end. This kind of expansion joint is called "expansion joint of deck sliding". |
