摘要
壁虎河大桥复建工程为扬州市重大民生工程.桥梁跨越省级流域性骨干河道壁虎河,该河为淮河入江水道,承担重要泄洪和排涝功能.主桥采用(41+150+41)m三跨连续钢箱系杆拱结构,桥梁采用少支架拼装施工,桥梁布跨和施工方案已充分考虑河道的排泄影响.通过主要介绍跨壁虎河三跨连续钢箱系杆拱桥的总体设计、结构设计、结构计算、施工方案等内容,为类似工程提供参考和借鉴.
Abstract
The reconstruction project of Gecko River Bridge is a major livelihood project in Yangzhou City.The bridge spans the provincial backbone river-Bihu River.This river is a water channel into Huaihe River and plays an important role in flood discharge and waterlogging drainage.The main bridge isa41m+150m+41m three-span continuous steel box bowstring arch structure.The bridge is constructed by the less-support assembly method.The drainage impact of the river channel has been fully considered in the span layout and construction scheme of the bridge.The overall design,structural design,structural calculation and construction scheme of three-span continuous steel box bowstring arch bridge spanning the Bihu River are mainly introduced,which provides reference for similar projects.
