摘要
太原市南中环汾河桥是跨越汾河连接太原市东西城区的重要桥梁。主桥为(60+180+60)m下承式连续拱梁组合体系结构,拱肋由主拱和副拱形成月亮造型。通过太原市南中环主桥主、副拱肋制作工艺研究,对拱肋的制作方法"以直代曲"分段焊接法和热煨弯成型法进行了详细介绍。
South-mid-ring Fen River Bridge is an important urban bridge on south-mid-ring of Taiyuan city over Fen River.The main bridge was designed as through type continuous arch-beam combination systems with the（60＋180＋60）m spans.The main arch and the assistant arch make up the architectural shape of the＂moon＂.The fabrication technic of the main arch and assistant arch is studied.The fabrication technics of arch rib,include using the straight line replace the curve line of subsection welding and heat-bending treatment are introduced in details.
