If viaduct approach spans are considered then perhaps the approach piers could be used to anchor the backstays . 如果設計中考慮高架引橋,則引橋的橋墩可用來錨定后拉索。
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1,000,000輛車就在系桿拱的橫梁中以及引橋的板梁中造成明顯的開裂。
