成渝公路内江新龙坳立交桥，在提篮拱体系．钢管混凝土劲性骨架．交叉吊杆．骨架侧转施工、管心混凝土泵压灌注等方面．开展了研究和实践；对大跨度拱桥的新材料、新结构、新工艺应用进行了成功的探索，本文就此表达了作者的见解。
To construct the XinLongao overpass bridge in Neijiang on the Cheng-Yu way.We have researched and practiced in the X-arch system,refovced frame of concrete-filled steel pipes.interluce crane beams system,constraction of frame by Changing a dip angle,pouringmiddle-pipe concrete by pumps and other fields.We have achieved great success in the exploration of new material、structure and technology.for super-large pattern.Based on these,we report our research work and practice work in this paper on the deVelopment of super-large arch bridge.
