大跨径简支组合拱桥施工技术

The construction technology of long span simply-supported composite arch bridge

以某简支组合拱桥施工为工程背景,对大跨径简支组合拱桥桩基、承台和现浇梁施工技术,拱肋吊装与拱肋焊接工艺等进行了详细介绍,为同类工程施工提供参考。

Take the simply supported composite arch bridge construction as background, construction technology of pile foundation, cushion cap and casting beam is introduced. A detailed introduction of arch rib hoisting and welding technology is put up forward, it can provide a reference for similar engineering construction.
