| 摘 要： | 为满足桥面变形的要求,通常在两梁端之间、梁端与桥台之间或桥梁的铰接位置上设置伸缩缝。长珲高速公路图珲段03合同段密江大桥全桥设有桥面伸缩和桥头伸缩,为确保伸缩缝施工质量,混凝土采用高性能混凝土。文中就密江大桥C50伸缩缝高性能混凝土配合比设计全过程做以详细论述。

| Abstract: | In order to meet the requirement of bridge deformation,the hinged joints are usually set between the ends of two beams,beam end and the abutment,or on the joints position of bridge.On the Tuhui highway map 03 River Bridge contract segment,the bridge deck expansion and bridge end expansion are set for full-bridge.High-performance concrete is adopted to ensure quality of construction.In this paper,the high-performance concrete mix design process for the expansion joint on the Middle River Bridge C50 were expl... |
