新疆拟建110 m 全向可转动望远镜，亦称奇台射电望远镜(QiTai radio Telescope, QTT)，其高灵敏度、高指向精度要求使其在结构上面临诸多挑战。如结构形式、重量与刚度、最佳电性能与天线精度、天线轨道、反射面分块等，如何在建设之前解决关键技术问题至关重要。列举了QTT 天线结构关键技术挑战，包括结构形式、反射面分块、焊接轨道，并对目前已有进展进行了总结。

A 110 m aperture fully steerable radio telescope named QTT (QiTai radio Telescope) will be built in Xinjiang. QTT’s structure will meet many challenges for its high sensitivity and pointing accuracy, such as structure type, weight vs stiffness, best electrical performance with antenna accuracy, track, reflector surface dividing strategies etc. How to resolve these questions before construction is important for QTT project. In this paper, we summarize some key challenges about QTT structure including type of structure, reflector surface division, track welding. Finally we present the progress we have already done.
