if viaduct approach spans are considered then perhaps the approach piers could be used to anchor the backstays . 如果設(shè)計(jì)中考慮高架引橋,則引橋的橋墩可用來(lái)錨定后拉索。
only 1, 000, 000 vehicle crossings produced significant cracking in the floor beams of the tied arch span and in the plate girders of the approach spans . 僅通過(guò)1,000,000輛車(chē)就在系桿拱的橫梁中以及引橋的板梁中造成明顯的開(kāi)裂。
