求翻译：An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more econom是什么意思？ 待解决

一座拱桥是有作为一个流线型的拱被塑造的每一端的接界处的一座桥。拱通过到在每个边被接界处限制的水平刺中部分传输桥的重量和其负荷克服工作。一 viaduct( 一座长桥 ) 可能由一系列拱制成，虽然其他更节约的结构通常今天被使用。
