| 摘 要： | 泸定水电站尾水大桥横跨发电厂房尾水渠,上部为连续预应力箱梁结构.为满足上、下游接线需要,尾水大桥采用弯箱梁,纵坡达4%.因转弯半径小,纵坡大,桥墩较高(最大高度达34.5 m),底板地质条件较差,与厂房施工干扰较大,施工难度大.经过分析论证,最终采用满堂支架施工方案,顺利完成了施工任务,满足了进度要求.

| Abstract: | The upper part of the bridge across the tail water of Luding Hydropower Station adopts pre-stressed continuous box girder to construct.In order to connect with existing road,the box girder must be curved in the horizontal plane,and at the same time,it has a sloping surface with a grade up to 4% in longitudinal direction of bridge.The construction of bridge is difficult because of smaller turning radius,steeper surface,high piers(maximum height of 34.5 m),poor geological conditions and interferences with pow... |
